Puccini Messa di Gloria

[MalinTrumpet]

Each transposition starts to develop it’s own “character”:
I practice Rochut from the original trombone book. I just read bass clef and play an octave higher. I’m working on a Bousquet etude on my C trumpet. I’m just used to reading Bb parts on a C. I really don’t use any particular method: I “just do it”. I recently purchased a G trumpet. I find that Broiles’s Eb etude book works wonderfully on a G transposed a major 3rd down. I could use soprano clef but I don’t really know how I do it.

Thanks Gentlemen.
For the beginning, a mixture of intervals and keys seems closer to what I am used to practice than by numbers...But ok, I understand the interest of all the methods.
By the way I found this very interesting:

Regarding Puccini, I will work with with the C part AND the original part.
I think it is a good start.
