“A spectrogram is a visual representation of the spectrum of frequencies in a sound or other signal as they vary with time or some other variable”

Spectrograms are a way to visualise sounds on a time/frequency axis.

You can use a spectrograph to visual any sound, but what if you reversed that idea and used an image as a spectrogram to create sound.

Mayu now has a large number of xrays, mammograms and scans. That so happen to look, just a little, like a spectogram.

So with this principle in mind, I am composing a long and major piece of music created entirely from the X-rays and scans of Mayu’s diagnosis and treatment.  Here is a sample, created using the image of a full body scan.
