Scales

What this section teaches

A scale is not a list of notes — it is a repeating pattern of steps, and the pattern is the identity. The major scale's whole-whole-half-whole-whole-whole-half recipe produces the major sound from any starting note; change one step and you get a different scale with a different personality. That is why this section documents twenty-four scale types rather than hundreds of individual scales: master a formula once and you own it in all twelve keys. The catalog spans seven families — the common major and minor scales, the five-note pentatonics, the blues scale, the seven modes, the bebop passing-tone scales, the perfectly symmetric patterns, and a set of world scales with distinctive augmented-second colors.

How to use these pages

Each scale's page states its interval formula, its scale degrees, its character, and its aliases — then spells the actual notes from any tonic you choose. Use it formula-first (how is harmonic minor different from natural minor? one raised seventh) or sound-first: read the description, pick the scale whose character you are hearing, and check its notes against the music in front of you.

Where to go next

Rotating one pattern through its seven starting points produces the modes; committing to one scale as home base creates a key; and if you have notes but no name, the scale finder works backwards from the notes you give it.
