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.
