Description

 

Philip Glass is one of my favorite composers and musicians. I knew I wanted to design an artifact that involved sound, and decided to create a glass that when picked up would play a song in the style of Philip Glass' repetitive and slowly modulating pieces. I composed the song on my trumpet at first and transposed it as best I could.

So this is my Ode to Philip::: Glass.

/* Ode to Philip::: Glass

* -----------

*

* This program is designed to work play a melody similar to that of

* composer Philip Glass. Whenever the light sensor is activated

* the melody is played once through.

*

*

* The calculation of the tones is made following the mathematical

* operation:

*

*       timeHigh = 1/(2 * toneFrequency) = period / 2

*

* where the different tones are described as in the table:

*

* note frequency period PW (timeHigh)

* c 261 Hz 3830 1915

* d 294 Hz 3400 1700

* e 329 Hz 3038 1519

* f 349 Hz 2864 1432

* f# 369 Hz                  1353

* g 392 Hz 2550 1275

* a 440 Hz 2272 1136

* b 493 Hz 2028 1014

* C 523 Hz 1912 956
