 | | All triads and 4-voice chords are built within the octave, or eight-note scale which encompasses the do-re-mi-fa-sol-la-ti-do of the major scale, for instance, or the scale steps 1-2-3-4-5-6-7-8; eight being the octave where the pattern starts over again. |
 | | This works for any scale, and whether the chord formed is minor or major depends on the scale: the I, IV, V chords are major, and the rest are minor, with the seventh being diminished. |
 | | The Neapolitan chord, for example, is an ordinary major chord, but its root is the lowered supertonic of the corresponding key, so the the Neapolitan of C major is a Db major chord. |
