Depending of certain requirements and, of course of the player’s level, these important
aspects could be considered as they follow:
An extra B key in footjoint isn’t necessary,
at least for students. Advanced players may get it when they need a broad reper- toire that includes a 1/2 step lower note.
It’s a matter of comfortableness to
reach the G key with an offset of it. Or,
instead of ergonomy, an in-line key is
just presenting an optional feature.
Covered holes are a very good choose for beginners. For those advanced players, ring holes are a guarantee to get a better control of their tone.
