I just saw, and enjoyed, Woody Allen’s Melinda and Melinda. At one point someone played Bach’s Prelude II from the Well Tempered Clavier. I recognized that I had played that once long ago but couldn’t remember the title. When I got home I discovered that I had forgotten most of the music. Barlow’s “Dictionary of Musical Themes” identified it. I found the sheet music online.
The patterns of the music are quite strict and suggest a custom program to perform the music, via MIDI. Here is a small program to perform the prelude, based on my general MIDI output routines. The routine Prel produces a MIDI file with style parameters, a bit like an html style sheet. The main routine as it stands produces this, which attempts a faithful transcription of the sheet music, and several more. This accentuates lead notes in a phrase. This is unreasonable fast but with the accentuated notes reveals to me another theme. This is fast and overlaps 16th notes. This is slower but with staccato filler.
The program may be run thus from a Unix shell:
gcc -Wall P2.c w.c r.c ./a.outYou will need h.h in your directory.
Below is an an ascii image I consulted for the project. It is the musical staff for 3 flats.
- 84 83 - 81 79 ----- 77 76 ----- 74 72 ----- 71 69 ----- 67 65 ----- 64 62 - 60 59 ----- 57 55 ----- 53 52 ----- 50 48 ----- 47 45 ----- 43 41 - 40 38 - 36 35Run this program thus scale n for n sharps and scale -n for n flats.
