Tonic, scale degrees and key

Find home first — then every note's position makes sense.

The tonic is the centre

The tonic is the tonal centre the music revolves around — not simply the most frequent note, and not necessarily the first or highest note. The key-setting cues here help you establish the centre first; in real music you also weigh harmony, accents, phrase endings and melodic direction.

Note names change; degree relationships stay

In C major 1 = C, 2 = D, 3 = E; in G major 1 = G, 2 = A, 3 = B and 7 = F♯. Think of “1” as the current tonic, not as a permanent name for C. You can show numbers, solfège or note names here; practising in new keys checks whether you really hear the relationships.

Degrees vs intervals

A degree describes where one note sits in the current scale; an interval describes the distance between two notes. C to E is a major third — in C major that's 1 to 3, in G major it's 4 to 6. Recognising intervals helps, but functional listening also hears each note's relationship to the tonic.

Stability isn't a fixed emotion

Words like “stable” or “wants to go home” are listening cues, shaped by the current chord, rhythm, register, direction and style. Don't file any note as a “happy note” or a “sad note”. Practise in a clear key first, then take that experience into real music.
