Summary Investment Objective The fund seeks as high a level of current income exempt from federal income tax as is consistent with the preservation of capital. Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the fund or shares of other funds in the BNY Mellon Family of Funds that are subject to a sales charge. More information about sales charges, including these and other discounts and waivers, is available from your financial professional and in the Shareholder Guide section beginning on page 12 of the prospectus, in the Appendix on page A-1 of the prospectus and in the How to Buy Shares section and the Additional Information About How to Buy Shares section beginning on page II-1 and page III-1, respectively, of the fund's Statement of Additional Information.

The Example assumes that you invest $10,000 in the fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The one-year example and the first year of the three-, five- and ten-years examples are based on net operating expenses, which reflect the expense limitation agreement by BNY Mellon Investment Adviser, Inc. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 517 517 661 661 817 817 1270 1270 249 470 815 1787 149 470 815 1787 45 45 141 141 246 246 555 555 42 42 132 132 230 230 518 518 55 55 173 173 302 302 677 677 Portfolio Turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 19.60% of the average value of its portfolio. 0.1960 Principal Investment Strategy To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal bonds that provide income exempt from federal personal income tax and the federal alternative minimum tax. Municipal bonds are debt securities or other obligations issued by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, or multistate agencies and authorities. The fund invests at least 65% of its net assets in municipal bonds rated, at the time of purchase, A or higher or the unrated equivalent as determined by Insight North America LLC, the fund's sub-adviser. The fund may invest up to 35% of its net assets in municipal bonds rated, at the time of purchase, below A, including bonds rated below investment grade ("high yield" or "junk" bonds), or the unrated equivalent as determined by the fund's sub-adviser.The dollar-weighted average maturity of the fund's portfolio normally exceeds ten years, but the fund may invest without regard to maturity. A bond's maturity is the length of time until the principal must be fully repaid with interest. Dollar-weighted average maturity is an average of the stated maturities of the bonds held by the fund, based on their dollar-weighted proportions in the fund.The fund's sub-adviser focuses on identifying undervalued sectors and securities. To select municipal bonds for the fund, the sub-adviser uses fundamental credit analysis to estimate the relative value and attractiveness of various sectors and securities and actively trades among various sectors and securities based on their apparent relative values. The fund seeks to invest in several different sectors, and does not seek to overweight any particular sector but may do so depending on each sector's relative value at a given time.A rigorous sell discipline is employed to continuously evaluate all fund holdings. Current holdings may become sell candidates if creditworthiness is deteriorating, if bonds with better risk and return characteristics become available, or if the holding no longer meets the sub-adviser's strategic or portfolio construction objectives.Although the fund seeks to provide income exempt from federal income tax and the federal alternative minimum tax, income from some of the fund's holdings may be subject to these taxes. <div style="border-bottom:0.25pt; border-bottom-style:solid; border-bottom-color:#000000; margin-top:12pt; padding:0pt 0pt 1pt 0pt;"><div style="font-size:12.0pt; font-family:Arial; text-align:left; color:#000000; font-weight:bold;">Principal Risks</div></div>An investment in the fund is not a bank deposit.

The fund's share price fluctuates, sometimes dramatically, which means you could lose money. · Municipal securities risk: Municipal securities are subject to interest rate, credit, liquidity, valuation, market and political risks. The amount of public information available about municipal securities is generally less than that for corporate equities or bonds. Special factors, such as legislative and regulatory changes, executive orders, voter initiatives, and state and local economic and business developments, may adversely affect the value of the fund's investments in municipal securities. Other factors include the general conditions of the municipal securities market, the size of the particular offering, the maturity of the obligation and the rating of the issue. Changes in economic, business or political conditions relating to a particular municipal project, municipality, or state, territory or possession of the United States in which the fund invests may have an impact on the fund's share price. Any credit impairment could adversely impact the value of municipal bonds, which could negatively impact the performance of the fund. In addition, income from municipal securities held by the fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of an issuer or other obligated party. Loss of tax-exempt status for municipal securities held by the fund may cause interest received and distributed to shareholders by the fund to be taxable and may result in a significant decline in the values of such municipal securities. · Interest rate risk: Prices of bonds and other fixed rate fixed-income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed-income securities and, accordingly, will cause the value of the fund's investments in these securities to decline. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy, rising inflation and changes in general economic conditions. It is difficult to predict the pace at which central banks or monetary authorities may increase (or decrease) interest rates or the timing, frequency, or magnitude of such changes. During periods of very low interest rates, which occur from time to time due to market forces or actions of governments and/or their central banks, including the Board of Governors of the Federal Reserve System in the U.S., the fund may be subject to a greater risk of principal decline from rising interest rates. When interest rates fall, the fund's investments in new securities may be at lower yields and may reduce the fund's income. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from fund performance. The magnitude of these fluctuations in the market price of fixed-income securities is generally greater for securities with longer effective maturities and durations because such instruments do not mature, reset interest rates or become callable for longer periods of time. Unlike investment grade bonds, however, the prices of high yield ("junk") bonds may fluctuate unpredictably and not necessarily inversely with changes in interest rates. · Credit risk: Failure of an issuer of a security to make timely interest or principal payments when due, or a decline or perception of a decline in the credit quality of the security, can cause the security's price to fall. The lower a security's credit rating, the greater the chance that the issuer of the security will default or fail to meet its payment obligations. · High yield securities risk: High yield ("junk") securities involve greater credit risk, including the risk of default, than investment grade securities, and are considered predominantly speculative with respect to the issuer's ability to make principal and interest payments. These securities are especially sensitive to adverse changes in general economic conditions, to changes in the financial condition of their issuers and to price fluctuation in response to changes in interest rates. During periods of economic downturn or rising interest rates, issuers of below investment grade securities may experience financial stress that could adversely affect their ability to make payments of principal and interest and increase the possibility of default. · Liquidity risk: When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities and the fund's share price may fall dramatically. The secondary market for certain municipal bonds tends to be less well developed or liquid than many other securities markets, which may adversely affect the fund's ability to buy or sell such municipal bonds at attractive prices. Investments that are illiquid or that trade in lower volumes may be more difficult to value. The market for below investment grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline. · Prepayment risk: Some securities give the issuer the option to prepay or call the securities before their maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity. Issuers often exercise this right when interest rates fall. If an issuer "calls" its securities during a time of declining interest rates, the fund might have to reinvest the proceeds in an investment offering a lower yield, and therefore might not benefit from any increase in value as a result of declining interest rates. During periods of market illiquidity or rising interest rates, prices of "callable" issues are subject to increased price fluctuation. · Valuation risk: The price that the fund could receive upon the sale (or other disposition) of an investment may differ from the fund's valuation of the investment, particularly for investments that trade in lower volumes, investments that are valued using a fair valuation methodology or a price provided by an independent pricing service, or during market turmoil or volatility. As a result, the price received upon the sale of an investment may be less than the value ascribed by the fund, and the fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. · Market risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, recessions, elevated levels of government debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events could have a significant impact on the fund and its investments. · Management risk: The investment process used by the fund's sub-adviser could fail to achieve the fund's investment goal and cause your fund investment to lose value.

Municipal bonds rated below investment grade (BB/Ba or lower) are commonly known as "high yield" or "junk" bonds. These bonds typically offer higher yields than investment grade bonds, but involve greater risks, including the possibility of default, and increased market price volatility.

The market for below investment grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline. · Rule 144A securities risk: Rule 144A securities are restricted securities that, while privately placed, are eligible for purchase and resale pursuant to Rule 144A by "qualified institutional buyers," as defined under the Securities Act. The market for Rule 144A and other securities exempt from certain registration requirements typically is less active than the market for publicly-traded securities. As such, investing in Rule 144A securities may reduce the liquidity of the fund's investments, and the fund may be unable to sell the security at the desired time or price, if at all. The purchase price and subsequent valuation of Rule 144A securities normally reflect a discount, which may be significant, from the market price of comparable unrestricted securities for which a liquid trading market exists. · Prepayment risk: Some securities give the issuer the option to prepay or call the securities before their maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity. Issuers often exercise this right when interest rates fall. If an issuer "calls" its securities during a time of declining interest rates, the fund might have to reinvest the proceeds in an investment offering a lower yield, and therefore might not benefit from any increase in value as a result of declining interest rates. During periods of market illiquidity or rising interest rates, prices of "callable" issues are subject to increased price fluctuation. · Valuation risk: The price that the fund could receive upon the sale (or other disposition) of an investment may differ from the fund's valuation of the investment, particularly for investments that trade in lower volumes, investments that are valued using a fair valuation methodology or a price provided by an independent pricing service, or during market turmoil or volatility. As a result, the price received upon the sale of an investment may be less than the value ascribed by the fund, and the fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. · Market risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, recessions, elevated levels of government debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events could have a significant impact on the fund and its investments. · Management risk: The investment process used by the fund's sub-adviser could fail to achieve the fund's investment goals and cause your fund investment to lose value. Performance The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Class Z shares from year to year.
