Lower strings, brass and bass clarinet create a nightscape of sorts; played against them are agonizingly high harmonic tones on the solo instruments.

Musicians have long prized its ability to project a full range of harmonic tones, but instrument makers have never been able to duplicate the sound.

Random noise is typically less objectionable than the harmonic tones produced by limit cycles.

Depending on where the string is played, a bell-like harmonic second tone is created.

At this, Jack feels an odd, deep chill, as if many worlds had spoken in a harmonic tone, low but resonant.

Purely harmonic tones cause neural firing exactly with the period or some multiple of the pure tone.

The added harmonic tone is lower, at about 1-5% or less in a no feedback amp at full power and rapidly decreasing at lower levels.

Hammond organs also have a harmonic percussion effect, in which the 2nd and 3rd harmonic tones can be added to the attack envelope of a note.

The right drum head has a circular disk in the centre called karne causing the drum to produce harmonic tones.

This technique is used to produce harmonic tones that are otherwise inaccessible on the instrument.
