Expenses [Text Block] | What were the Fund’s costs for the last year ? (based on a hypothetical $10,000 investment) Share Class Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment Class A * $ 0.80 % * During the period, fees were waived and/or expenses reimbursed pursuant to an agreement with the Fund’s investment adviser, BNY Mellon Investment Adviser, Inc.

Factors Affecting Performance [Text Block] | How did the Fund perform last year ? For the 12-month period ended November 30, 2024, the Fund’s Class A shares returned 5.59%. In comparison, the Bloomberg U.S. Municipal Bond Index (the “Index”) returned 4.93% for the same period. What affected the Fund’s performance? Municipal bonds produced solid returns, buoyed primarily by a summer rally in anticipation of Fed interest rate cuts. Strong inflows to mutual funds and robust credit conditions also provided support. With the exception of the 7-10 year maturities, municipal yields declined, following U.S. Treasury yields lower. Longer-maturity municipal bonds performed best. The hospital, airport, prepaid gas and tobacco securitization sectors contributed most, followed by an underweight to pre-refunded bonds. An underweight to New York City general obligation bonds also enhanced results, as did exposure to 15-20 year maturities. Essential services bonds, including water & sewer, transportation and public power, detracted from performance. A modest overweight to 10-year maturities also hampered returns. Not FDIC Insured. Not Bank-Guaranteed. May Lose Value | |

Material Fund Change [Text Block] | How has the Fund changed? On May 17, 2024, the Fund commenced offering Class Z shares. Effective May 17, 2024, BNY Mellon Investment Adviser, Inc. (the “Adviser”) has contractually agreed, through March 29, 2025, to waive receipt of its fees and/or assume the direct expenses of Class Z shares so that the direct expenses of Class Z shares of the fund (excluding shareholder services fees, taxes, brokerage commissions, interest expense, commitment fees on borrowings and extraordinary expenses) do not exceed .55%. To the extent that it is necessary for the Adviser to waive receipt of its management fee or reimburse the fund's common expenses, the amount of the waiver or reimbursement will be applied equally to each share class of the fund. On or after March 29, 2025, the Adviser may terminate this expense limitation agreement at any time. As of the close of business on May 17, 2024, pursuant to an Agreement and Plan of Reorganization (“Reorganization”) previously approved by the Fund’s Board of Trustees (the “Board”), all of the assets, subject to the liabilities, of BNY Mellon New York Tax Exempt Bond Fund, Inc. (the “Acquired Fund”) were transferred to the Fund in a tax free exchange at cost basis for Class Z of Common Stock of equal value. The purpose of the transaction was to combine two funds with comparable investment objectives and strategies. Shareholders of the Acquired Fund share class received Class Z shares of the Fund in an amount equal to the aggregate net asset value of their investment in the Fund’s Class Z shares at the time of the exchange.
