The CT Collective was started by Michael Klobuchar using cassettes (remember them?) The group members contributed music by mailing a master tape which was distributed to the members as a CD. No one got paid for any of this! I found it a great creative stimulus, creating music to fit the theme and hearing how others interpreted it.
A harmonic is “an overtone accompanying a fundamental tone at a fixed interval, produced by vibration of a string, column of air, etc. in an exact fraction of its length”. My first encounter with them was as a teenager, watching mystified as Rory Gallagher moved his hands down the neck but the notes played got higher! I eventually learned what they are and to this day, remain fascinated by the bell-like purity of guitar harmonics. For this project, harmonics of any kind were deemed acceptable, even “comb filter resonance” which Michael Peters assures me are harmonics.
My track “Ahhhh, Monique!” is a telecaster, tuned to E F C G B C generated all the harmonics on this track using fingers and a violin bow. Post-processed and arranged using Ableton Live and is available here.
