Is chance inspiration?

Maybe sometimes?


Many inventions were made by accident. For example the post-it stickers made from failed glue experiments.


Does it happen to music composing too?


For example, we know the Pink Floyd were playing, jamming for an hour or so E minor to A major while Breathe from Dark Side of the Moin was being developed. Could it be that at some point Roger Waters played C on bass instead of E thereby creating the fabulous sounding C major seventh chord, C E G B? It's so nice, let's keep it.


A simple melody could also be made by a keyboard playing the wrong notes.


This is how Semele was created. The keyboard used had been bought from a yard sale for 1 euro. It is so deliberate cheap and toy that it played the wrong notes. Instead of playing C it would play for example F. The nice inspirational keyboard is Soupeb Sound Audio Products model EK-210.


So by chance, this is the melody that came when trying to playi on it.

Key is D minor so every B is B flat.


Bass code is B then G7 then D then C246 back to B.


Ie BbDF, GBbDF, ADF, ACDF back to begining.
