Music theory

Two guides engraved with LilyPond, to be read in order. Intervals: naming, measuring and inverting them. Scales: the major scale as two tetrachords joined by a tone, the circle of fifths that follows from it, and the three forms of the minor scale.

Listen to them in Sodor Piano, which scrolls the score as it plays, or download them for MuseScore, Finale, Sibelius, Dorico or any score editor.

Music theory

The examples of both guides, in reading order: the intervals, each played one note after the other, then both notes together; then the scales, in all fifteen keys, ascending then descending, with their key signature.
