Bordogni FAQ Q: How "complete" are these books? A: Both the Trombone book and the Tuba book contain all 120 of Bordogni's vocalises. Q: What happened to étude number one? A: These books contain Bordogni's étude number one. The first étude in the old Rochuet edition was not written by Bordogni. Q: How many études in the trombone book are in either tenor or alto clef? A: Études 60-120 appear in either tenor or alto clef. Q: Is there a recording of the accompaniments available from Encore? A: No. We believe it is better to practice these vocalises without a recording. Learning to interpret the music is one of the most important reasons to use Bordogni's vocalises. Playing along with a recording does not allow the freedom needed to properly interpret the music. Q: Can the études in the tuba book be played on an F tuba? A: Yes. They can, and should, be practiced on both the high (F or E^b) and low (CC or BB^b) tubas. Q: I play the tuba. Should I just transpose the études from the trombone book down one octave? A: No. It is much better to play the notes you see on the page "at pitch". This correctly develops the "eye-ear-finger-embouchure" response. This is especially important when learning a new instrument such as the high (F or E^b) tuba. Transposing music while trying to learn a new instrument (i.e. new fingerings) will delay the learning process. Q: Are the key signatures the same as the Rochuet/Bordogni books? A: Yes. Both the tuba book and the trombone book use the same keys as the old Rochuet edition. The Mulcahy trombone book also notes all differences from Bordogni's original keys.
