I composed this piece for the "Seven-String" Guitar. It's called "SlowSeven". While I am on the "Autistic Spectrum", playing this instrument has always come natural--playing since 12, fast since 14.
This video introduces a creation of mine called the "GuitarShredCam". It is a system to capture images of guitar performance. At this time it is currently NOT FOR SALE, as it is undergoing further development.
