Scales and Keys
Major and minor scales, keys, sharps and flats
A scale is a selection from the available pitches, and choosing which notes to leave out is what gives music from different traditions its distinctive character.
The unit covers the major scale and its pattern of tones and semitones, minor scales, sharps and flats, key signatures, and the tonic as home.
This unit breaks down into 23 short steps and 119 questions, starting at difficulty 1 and building to 5. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

Where this fits
Needs Pitch and Melody and Reading Music. Required for Intervals and Chords.
Where people slip
Major and minor are patterns of intervals, not lists of notes. The same set of white keys is C major or A minor depending on which note behaves as home.
How the unit is structured
Scales and Keys runs as 23 short steps that unlock in order. 17 are practice rounds and 6 are challenge rounds that pull together everything before them. Questions start at difficulty 1 and climb to 5 as you progress.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
