Is the function of an 'Arpeggio ( 1-3-5-b7 ), the same as a 'Tetra-Chord'?
I don't believe so. The definition of a tetrachord is:
A scale of four notes, the interval between the first and last being a perfect fourth.
The interval between the first and last note in your example is a minor seventh. I think this would more closely resemble a tetrachord: 1 - 2 - b3 - 4
Thanks Garrett... I agree. I saw some "guitar teacher" that described an 'Arpeggio', as a Tetra-Chord', and I needed a credible confirmation, that he was wrong... That's seems to be an online problem, ( teachers giving wrong information ). Thanks again.
