2Appearance: diagrams and sound

Tip: click any note, key or fret to hear it. Orange = root.

3Indications: what it is used for

The foundation of pop, rock, country, folk, classical and most children's songs. Play it over major-key progressions such as I–IV–V, I–V–vi–IV and I–vi–ii–V, and over a major or major seventh chord on the tonic. Every other scale and mode is usually described as an alteration of this one, and chords, key signatures and interval names are all measured against it. Use it for melodies, harmony lines in thirds or sixths, bass lines that walk diatonically, and as the parent scale for the seven modes.

4Dosage: how to practise it

Ten minutes a day. Start at 60 BPM in quarter notes, two octaves up and down, then move to eighth notes and raise the metronome by 4 BPM once it feels clean. Practise sequences: groups of three (1-2-3, 2-3-4...), groups of four, and diatonic thirds (1-3, 2-4, 3-5...). On guitar, learn it in five CAGED positions or the three-notes-per-string system and connect them along the neck. On piano, use the standard fingering with the thumb passing under after the third or fourth finger, hands separately first, then together in parallel octaves.

5Warnings and common mistakes

Do not confuse the scale with its key signature: the scale is the order of notes, the key is the tonal centre. Beginners often rush the half steps and play a flat or sharp in the wrong place when changing roots, so spell the scale by its formula (whole, whole, half, whole, whole, whole, half). The fourth degree clashes with the major third of the tonic chord when held over it, so treat it as a passing note on strong beats. Starting the same notes from the sixth degree gives the relative minor, not a new major scale.
