Pianogram - histogram + piano notes = pianogram; select from existing pieces or import your MIDI file. A part of Joey's Visual Playground.

Useful? Maybe.

Kind of brilliant? Yes.

I was trying to guess the key from the pianogram.
50-50 so far.

I... I THINK I have a midi around here somewhere...

I wonder how it would handle some black midi scores. (previously)

Found one!

48 million notes, about 400MB. I think I broke the website. Although to be fair the demonstration video shows the file bringing the MIDI player down too. By 40 seconds in the playback devolves to some weirdass hybrid of 1950s-era 12-tone music and John Cage-style random event scoring.

It took maybe 50 minutes, but the black midi pianogram was rendered.

Kudos!

Not meaning to threadjack this, so I'll leave this one last item: List of largest MIDIs. Somewhere out there is a 280 billion note version. It must sound like white noise.

It must sound like white noise.

If it does, its pianogram would be a nice visual check that it is really random.

An option to use color for the same note in different octaves would help. And alternately, using color to indicate harmonic distance of notes within a user-selected key. (So for C, C is yellow and G is yellowish and C# is freakin' purple or something.)

The black midi pianogram I posted is impressively close to white-noise evenness. Aside from two ridiculous spikes (low A and low E♭), the notes are distributed relatively evenly, though biased towards the lower half of the range.
