I've heard this sequence of tones before. It was on a cassette tape that had
music on it, and on a two-inch master reel that had been used to record a band
I played in.
I think it had something to do with sync. I don't know why I didn't ask the
engineer what it was for. But that's the only thing I can think of.

Hi,
Very interesting indeed.
The tones themselves are sine waveforms, and had it not gone through a series
of straight octave changes I would have called it an arpeggiated harmonic
sequence. As it happens I have never heard that sequence before, on tape or
otherwise
The only tones I have heard are the really low tones that are meant to serve
as a marker to cue-and-review enabled tape players and sometimes used by
autotrack tape players. I’m guessing that sequence has a similar functionality,
some kind of unique marker, but I doubt an auto system would look for that.
Hope this helps.
Cheers.
Damien.

Or rather, series of tones? I usually hear these on some of the tapes I have,
at the beginning and end of each side. What do those tones do?
