5 tones (sine waves) of a simple pentatonic scale fade in and out at different rates.This process is arbitrarily cut off at around 1000 seconds.

I have made more of these scale phases, and you can find them here:

Ratios present in this scale:
1/1: root (200Hz)
3/2:P5
4/3:P4
7/4: m7
7/6: "m3"


pentatonic phases

The 12 tones of the standard equal-tempered chromatic scale fade in and out in different phases. Track is arbitrarily cut off at approximately 1000 seconds. Lowest pitch is 220Hz (A).

chromatic phases

The 7 tones of the standard equal-tempered A major scale fade in and out in different phases. Lowest pitch is A 220Hz. Audio file is arbitrarily cut off at approximately 1000 seconds.

major phases

The 9 tones (sine waves) of Steve Grainger's "tri-pentatonic" scale fade in and out in different phases. Track is arbitrarily cut off at about 1000 seconds. The root pitch is at 200Hz.

Grainger tri-pentatonic phases

The 14 pitches (sine waves) fade in and out at different rates. The pitches are those from one of Kraig Grady's 14-tone expansions of Steve Grainger's "tri-pentatonic" scale. The root pitch is at 200Hz. The audio file is arbitrarily cut off at approximately 1000 seconds.

See the following post from Anaphoria for more information on this scale, and a handy diagram:
