Charles Ives (1874-1954) founded Metropolitan Life and created the concept of life insurance as a tool of estate planning. His secret life as a composer was played out at home and at a church in New York where was organist.
His religious settings stretch the boundaries of tonality. This was a student exercise from his years at the Yale Music School. Half the chorus sings in G minor and the other half in C Major. It’s hard to make bi-tonality work – it’s still illegal in some states – but Charlie does a reasonable job.
I think that is still illegal in Florida!
(That is probably a good thing!) LOL!
