What notes are in A# natural minor?
A# natural minor contains A#, B#, C#, D#, E#, F#, G#. One octave is A#–B#–C#–D#–E#–F#–G#–A#. The final tonic repeats the starting note an octave higher.
Which notes change in A# harmonic and melodic minor?
Harmonic minor changes degree 7 from G# to G##: A#–B#–C#–D#–E#–F#–G##–A#. In the classical melodic-minor ascent, degree 6 changes from F# to F## and degree 7 is G##: A#–B#–C#–D#–E#–F##–G##–A#.
What is the descending classical melodic-minor sequence?
For the classical scale-exercise convention, descend A#–G#–F#–E#–D#–C#–B#–A#. In the displayed right-hand register that is A#5–G#5–F#5–E#5–D#5–C#5–B#4–A#4. Degrees 6 and 7 return to their natural-minor values, F# and G#. Do not simply reverse the raised ascending form; the jazz melodic-minor convention is a different choice.
Which fingers are supported for each hand and range?
Natural minor: right hand ascending 2–1–2–3–1–2–3–4; left hand ascending 2–1–3–2–1–4–3–2. Notes-only combinations: right hand descending, left hand descending. Harmonic minor: right hand ascending 2–1–2–3–1–2–3–4; left hand ascending 2–1–3–2–1–4–3–2. Notes-only combinations: right hand descending, left hand descending. Melodic minor (classical exercise): left hand ascending 3–2–1–4–3–2–1–3; left hand descending 3–4–3–1–2–3–1–2. Notes-only combinations: right hand ascending, right hand descending. All supported finger rows here cover one octave with hands separately. A missing row is not permission to reverse or borrow another form’s fingering.
How do I match the keyboard, score and printed note names?
First match the tonic, minor form, hand or view, direction and one-octave range. Then read the ordered note names with their octave numbers and compare each to the staff and highlighted key. The printout should state the same selection; a fixed PDF has its own named coverage. Keep written accidentals even when they share a physical key with another spelling.
Why are B#, E#, F## and G## retained instead of respelling the key?
A-sharp minor uses a distinct letter for each degree: A#–B#–C#–D#–E#–F#–G#. Harmonic minor raises G# to G##; classical melodic minor also raises F# to F## in ascent. B# shares a piano key with C, E# with F, F## with G and G## with A, but replacing those spellings would obscure the degree structure. In descent the classical exercise returns to F# and G#.
