Pentatonic scales are a fantastic starting point for melody writing. The pentatonic scale has two forms: MAJOR and MINOR. See the chart below to see how A minor pentatonic is played on the keyboard, this also shows how the scale overlaps with C Major pentatonic.
So, an A minor pentatonic scale contains these five notes:
A – C – D – E – G – (A) – I’ve included this top A because the scale sounds incomplete unless you go up the octave above the root note.
C major pentatonic is:
C – D – E – G – A – (C)
This is the most commonly used scale in rock music for improvising, guitarists know the scale well!
Many, many songs use pentatonics for melody, they are especially popular in contemporary R’n’B.
