Chapter overview
Minor scales offer several colors to explore. Changing just one or two notes can alter how a line approaches its tonic, so listening belongs beside learning the keys. Pay particular attention to the sixth and seventh degrees, and read the return independently when the ascending and descending forms differ.
Preparation: Know a one-octave scale and read the key signature and finger numbers.
Three sounds to recognize
Natural minor uses the key signature without raising degrees 6 or 7. Its whole-step approach from the seventh degree to the tonic gives a different sense of arrival from major.
Harmonic minor raises degree 7 to create a leading tone and support a major dominant chord. The augmented second between degrees 6 and 7 is its distinctive melodic gap.
Melodic minor, in the conventional classical scale exercise, raises both 6 and 7 ascending to smooth that gap, then uses natural minor descending. Actual minor-key melodies choose these notes according to harmony and direction; they do not obey a blanket rule that every ascent must be raised and every descent lowered.
Musical connection
Planned application: selected scale passages, including the Mozart and Beethoven candidates in the repertoire section; exact excerpts still need source review.
In this review edition: selected material follows. The development list describes the full intended chapter; unengraved exercises and unverified repertoire candidates remain planned.
1. Natural and harmonic minor
Purpose: hear and play the altered scale degrees without disrupting the pulse. A minor shares C major’s key signature, but A is its tonic. Start RH on A below middle C, LH an octave lower. These one-octave examples use the same finger sequence for all three forms.
Play A–B–C–D–E–F–G–A and return. Give the final A time to settle, then compare that arrival with C major’s arrival on C. The keys are familiar, but the place that feels like home has changed.
Harmonic minor raises degree 7: G becomes G♯. The larger gap F–G♯ is an augmented second. Give it the same time as every other eighth note; do not rush across it or stretch its duration.
Practice and listen
- Play F–G♯–A and A–G♯–F separately, using the printed fingers.
- Play the complete harmonic form without pedal, then the natural form.
- Sing the last three ascending notes of each. Hear G♯ lead into A.
Checkpoint: you can name which note changes, retain it on the harmonic descent, and keep a steady beat. Work hands separately if reading the accidental distracts from the crossing.
2. Melodic minor: read the return independently
In the conventional classical scale exercise, melodic minor raises degrees 6 and 7 ascending, then restores them descending. In A minor, ascend with F♯ and G♯; descend with G-natural and F-natural.
This is a practice convention, not a rule that every minor-key melody must follow. Composers choose altered notes to fit the harmony and direction of a phrase.
Three passes through the pattern
You do not need to solve notes, fingers, and phrasing in one attempt. Give each pass one main question, then bring the answers together.
- Notes first: say E–F♯–G♯–A, then A–G–F–E. Locate the two black keys before playing.
- Fingers next: rehearse each hand separately. The written fingering remains the same as the preceding natural and harmonic forms, even though the keyboard shape changes.
- Whole phrase: play up and down with one turn at A. Keep the natural signs on the descent in view; do not repeat the ascending pitch pattern backwards.
Listen for: both directions remain even, with a clear change in color on the return. If you accidentally play G♯ descending, stop and rehearse just the descending four-note group before trying the whole scale again.
Choose a form deliberately
Return to the three forms over successive sessions, listening for the difference each time. Before playing, name the form and its altered notes. Pair A minor with C major in the circle-of-fifths routine. Other minor keys need their own fingering checks; do not transfer A minor’s route to every key.
Next: the arpeggio chapter separates chord tones from the intervening scale notes. A minor’s tonic triad is A–C–E in all three forms above.
