The main reason this interests me is because of the connections that can be made with making any sound with the mouth. Not just words during speech. A topic of interest, beat boxing, comes to mind and has me sorting through the alphabet. Taking notice of what parts of the vocal tract are ignited at different times.
Also, the hearing of the alphabet in the simplicity of an instrumental track, with basic notes being played on different instruments. And so falls into the play the idea of tuning your instrument to certain letters. Ahaa…
I think tomorrow I will display some of my favorite tracks to listen to lately. Perhaps the goal will be to listen for those letters in the wavelengths.
