Mastering the Trumpet A♭ Major Scale
Written A♭ Major contains four flats (B♭, E♭, A♭, D♭) and sounds as Concert G♭ / F♯ Major on B♭ trumpet. Starting on resonant Low A♭3 (2 - 3) below the staff, it develops warm low-register air column control and crisp 1st-finger independence between D♭4 (1-2-3) and E♭4 (2-3).
