98 Harmonics Skip 5 is a piano solo using pianoteq and this scala file to play in a harmonic series segment tuning. The tuning is NOT normalized to an octave. It is the raw harmonic series. The full quality video can be downloaded from this folder http://micro.soonlabel.com/harmonic_series/

    Dear Chris,

    This is a very interesting piece. Lots of neat sounds. Thanks for sharing!

    Peace,

    Hi Bill, any sound, besides a sine wave, is made up of additional, quieter notes, called harmonics. Those harmonics are one of the ways the sound of an instrument is defined.

    When you do a filter sweep with a high Q (filter resonance) on your synthesizer what you hear are the notes of the harmonic series that is in your starting waveform. Adjusting the Q changes how loud those are.

    What I did here was copy the natural pattern of harmonics for one note and assigned each to a note on the keyboard. Since I have programs that do all of the grunt work for me it was easy to do. Maybe it will be clearer with this list of notes and frequencies:

    I think this is so foreign to most ears because they (I am guessing) do not know what to listen for? I think it is the harmonic tones that foretell what this piece is about… the harmonics one may never hear unless the tuning is tuned harmonically, I am hoping we are one the same page with this Chris?
