Gershwin's peace is in A notation
Bela Fleck played it wrong. It's not in C minor or E flat. It's in E flat minor or G flat. How do I know this? Well Gershwin most likely grew up listening to Classic banjo records. It's not like he was naive to the fact that banjos were transposed at the time. The evidence I have? Well one of the notes goes down to low A on the manuscript, a lot of the E flats are made natural which suits the fifth string on a five string banjo in A notation. Gershwin was more likely to use black key tonalities rather than keys like C minor because of their bluesy flavor. When he wrote this he was clearly thinking of people like Fred Van Epps. Bela Said he was thinking of a plectrum or tenor but that's not the case. The manuscript is clearly written for five string. Any questions?
