The shared foundation
Music theory,
from first principles.
The shared foundation. Notes, intervals, scales, chords — the theory every instrument depends on. No prior knowledge assumed, no sheet music required. Work through it once, and it underpins every instrument you'll ever pick up — bouzouki, guitar, voice, or anything else.
Start chapter 1 →Three parts, twenty chapters
- I
Foundations of sound
Pitch, the musical alphabet, the octave, and the 12 notes that everything else is built from.
- II
Intervals & scales
How notes combine into intervals, how intervals build scales, and how Roman numerals let us talk about either in any key.
- III
Chords
Where chords come from — stacking thirds on a scale — and how the seven triads of every key fall out of one simple rule.
