Of Course plays with the situation that is a feature of all string instruments--the chromatic scale that the frets define (0,1,2,3,4,5, etc.) multiplied by 5, base 12 = the series of open strings on the guitar. Start with the 6th string E and call that 0. 0 X 5 = 0 (E) The next chromatic note, the note on the (6) string, first fret is 1 (F). 1 X 5 = 5 5 semitones above E is A, the 5th string. The note on the 2nd fret on the 6th string is F#. F# is 2, as E is 0. 2 X 5 = 10 10 is D, the 4th open string of the guitar. The 3rd fret on the 6th string is G. 3 X 5 = 15 In base 12, 15 is reduced to 3. The 3rd string of the guitar, the next up from the D string, is the G string. There comes some complications with the anomalous major third between the 3rd and 2nd strings.
There is a companion piece, *Coursing Again*, for two guitars, which is Of Course (the whole piece) X 5 base 12, and then reworked considerably. It has yet to be recorded, but will be out soon.
