DESCRIPTION:
The 7-1-5 "Voicing" is not a voicing at all, but refers to playing the 7th, 1st and 5th degrees of a scale, which - when played together or arpeggiated - go well with many chords constructed on the same scale. For example, just playing a 7-1-5 with different bass notes will yield completely different voicings for known chords. In this video I'll outline the idea and show you how it works in context by playing some harmonic progressions for you to actually hear what it sounds like.

More About Chord Voicings from Wikipedia:

"In music composition and arranging, a voicing is the instrumentation and vertical spacing and ordering of the pitches in a chord (which notes are on the top or in the middle, which ones are doubled, which octave each is in, and which instruments or voices perform each). Which note is on the bottom determines the inversion. Voicing is 'the manner in which one distributes, or spaces, notes and chords among the various instruments" and spacing or "simultaneous vertical placement of notes in relation to each other.'"
