A Pentatonic Scale

From wiki,

“A pentatonic scale is a musical scale with five notes per octave, in contrast to the heptatonic scale, which has seven notes per octave”

Fyi, an octave refers to the interval between one pitch and another with double it’s frequency (from https://en.wikipedia.org/wiki/Octave)

On a regular western music scale that would look like this. (It would be referred to as a Heptatonic scale because there are 7 notes between Octaves)

A(1),B(2),C(3),D(4),E(5),F(6),G(7), then – A(8) again. (notice the 8? ie OCT-tave)

However, on a pentatonic scale, there are only 5 notes per octave.

In the key of A, which looks like this,

A(1), C(2), D(3), E(4), G(5), A

As a tab – it looks like this,

And it sounds like this,

Cheers!
