@stuartk I was curious about the word vocalese and its definition since there are a lot of classical music scores that use the word vocalise and the E instead of I after L, makes all the difference.
When you search query vocalise, the first thing that pops up is Rachmaninov.
When you query vocalese, AI generates this
Vocalese is a unique jazz singing style where vocalists write and perform original, often rapid-fire lyrics that perfectly match the notes, rhythm, and phrasing of pre-existing instrumental melodies or improvised solos
The posts by you and alek were the first I ever heard Annie Ross's vocals and I have to say she has that perfect female jazz tonality
