Ratio between pitch and length of an organ pipe: octaves.

This is a bass sound, not tuned but it is a perfect loop withouth clicks. It has no panning effect - i will do that on another sample. It is not tuned - use a program that tunes the samples to tonal. You must use it only in one octave from c5 to c6. In other octaves sounds not like a normal bass.

Sounds of the anordam, an experimental instrument that plays a 10-tone scale which consists entirely of perfect fractional divisions of the octave. The highest interval in the scale is 1/2, which means that for a given a value, half the octave will be left out of the scale.

Sum and difference tones of A220 and unison, just perfect fifth, and octave. Note that this is not produced through ring modulation of two notes, but is four separate notes.

This is a sawtooth waveform suitable for easily tuning guitar by ear, comprised of 20 seconds each of e-a-d-g-b-e in sequence. Adjust guitar volume to same volume as the tone, ideally through the same audio output. Tune the string close to the tone, then listen for the subtle beat-frequency indicating not-quite-perfect tune. When the beat frequency goes away, your guitar string is in perfect tune. Also useful for adjustable bridges. The open string and its 12th fret octave will both produce no beat-frequency when the bridge is adjusted properly.

Miracle scale, derived from the secor (s = 116.72 cents), plus the difference between 10 secors and a perfect octave (q = 32.84 cents). MIDI pitch bend appears to match intervals. The Miracle scale is 0 1 2 3 4 5 6 7 8 9 0' s s s s s s s s s s+q The difference between s and q (r) is used in the File:Blackjack scale.mid.

Blackjack scale, derived from the secor (s = 116.72 cents), the difference between 10 secors and a perfect octave (q = 32.84 cents), and the difference between that and a secor (r = s-q = 83.88 cents).
