Do You know some other books than Bordogni and Rachmaninoff with vocalises for tuba?

Concone etudes are good. Good practice for reading Treble Clef. The Pottag book for horn is also excellent and comprehensive.

Here a good collection of Concone, and some others (Panifka, for example)

Take a look at this collection in the public domain, including 100 vocalises in 3 volumes with accompaniments by Concone, Bordogni and others. Tubists would download the version for bass vocal--
