Yesterday my friend sent me a recording of a song. I was particularly stunned and interested in a scale (maybe not a scale, but it does sound like one.) I decided to upload the scale here: https://soundcloud.com/kris-pianist/scale. Trying my best, I cannot transcribe it. Can anybody please help me?
It's not a scale, it's a five-note-arpeggio. It is an Abminmaj9 ('A flat minor major nine') arpeggio. This chord has the notes
Ab Cb Eb G Bb
And on the recording it is played like this (from high to low):
Bb Ab G Eb Cb (and continued like this through 3 lower octaves)
The last note of the arpeggio (Cb, after descending 3 octaves) resolves to Bb, which is the root of the next chord (Bb major).
