Tetrachord

A Short Note On The Tetrachord

The term tetrachord has a Greek origin and can be broken down into two Greek words: tetra and chord.

It’s easier to understand the concept of the tetrachord on a string instrument like the violin. Therefore permit me to use the violin as a reference.

If you’ve been privileged to stand close to a violinist, you’ll observe that while they’re playing the major scale, they play four notes to a string. So for the entire major scale (let’s say the C major scale):

They’ll play the first four notes (which are C, D, E, and F):

…on a string, and the last four notes (which are G, A, B, and C):

…on another string.
