Minor Scales & Their Variants
Natural, harmonic, and melodic minor
The major scale is only half the story. Minor tonality, with its three distinct variants, is where the most emotionally complex music lives: Bach's D-minor Chaconne, Dvořák's cello concerto, Brahms symphonies. This module maps all three minor scale forms and shows you how to hear, play, and choose between them.

Write natural, harmonic, and melodic A minor
Minor scales have several conventional forms. Natural minor follows the key signature; harmonic minor raises scale degree seven. In the classical melodic-minor exercise, the ascending scale raises degrees six and seven, then the descent returns to natural minor.
Before you start: Use A minor, whose key signature has no sharps or flats. These are scale-writing conventions, not a claim that every minor melody must follow one form throughout.
- Natural minor letters: A–B–C–D–E–F–G–A.
- Harmonic minor task: raise degree 7.
- Classical melodic minor task: raise degrees 6 and 7 going up, restore them going down.
Try it step by step
- Number the notes from A = 1 to G = 7. Write the natural minor scale without changing any notes.
- Write harmonic minor by raising G to G♯. Keep F natural on both the ascent and descent.
- Write ascending melodic minor using F♯ and G♯, then descend with G natural and F natural. Check that the descending form ends on A.
Check your answer and understand why
Natural: A–B–C–D–E–F–G–A. Harmonic: A–B–C–D–E–F–G♯–A. Classical melodic ascending: A–B–C–D–E–F♯–G♯–A; descending: A–G–F–E–D–C–B–A. Harmonic minor retains its raised seventh when descending. Jazz melodic-minor practice commonly keeps the raised sixth and seventh in both directions, so name the convention you are using.
Common mistakes to avoid
- Do not raise F in harmonic minor; only degree seven is altered from natural minor.
- Do not add F♯ and G♯ to A minor’s key signature. They are alterations for these scale forms.

Planning this part of your learning
- Where should I start with minor scales & their variants?
- The curriculum places The Alto Clef & String Clefs before this module. Review those topics if they are unfamiliar. The first lesson is “The Natural Minor Scale”: The Aeolian mode as the foundation of minor tonality. The order is a study guide, not proof that every learner needs the same pace.
- How long is the minor scales & their variants module?
- The 5 listed lessons total approximately 75 minutes of material. That estimate describes lesson content, not the practice time needed to become comfortable with natural, harmonic, and melodic minor. Revisit one task at a time and use feedback from a teacher where physical technique is involved.
- What can I try here without an account?
- The complete “Write natural, harmonic, and melodic A minor” exercise, its worked answer and common mistakes are free on this page. The lesson list and linked public tools are also open. A free account includes the complete five-lesson foundation module in each instrument and five lessons in music theory, with saved progress and no expiry. Later lessons require the relevant paid package.
