It will be tuning. Having picked the standard (A=440Hz?) all instruments will be tuned to it, with harmonics and sub-harmonics as appropriate. Alternatively, the studios did some digital fiddling to get them all on pitch. Anyway, as your result came from a number of different performances the only way you could get such peaks and troughs is if the frequencies from all performances were all fairly accurately aligned. The troughs would be even lower if tuning was perfect, or vibrato was not used (e.g. on some 'original instruments' performances).

Interesting work. What about Electronic Music (Westbam, Tiesto, Picotto, van Dyk, Oakenfold, Darude, Sasha, Digweed, etc.)?

Sorry about the last graph, posted the wrong graphic! Here is the correct one with peaks vs average.

OK, thanks. When I first looked at it they frequency peaks intrigued me, thinking they must be discreet notes and harmonics. But that didn't seem likely averaged over 100+ tracks (fewer than 100 recordings).

Perhaps this shows us that some types of music really are noise.

Very few classical orchestras use A440 except the british and lesser american ones. Everybody else uses A442-445.
Baroque music has it as A415.

OK, I looked at some current EDM/Dance/Trance tracks. The results are below.
The EDM bass content is 30 dB above 1kHz! Rock is 15 dB over 1 kHz. The peak for EDM is 46-48 Hz, or a low F# or G (fa-sol)

looks like a subwoofer is must for EDM/Dance/Trance. And one can safely discard super tweeter for most music genres.
When tuning instrument do they take in to account The Fletcher Munson Curve ? Any online guide to standards used in the recording studios, live programmes of tuning/recording levels ?
Regards.

Just checked Wikipedia. It says that 440Hz is the only official standard, but some orchestras go a bit higher - so 'pitch inflation' is still with us!
