C medium Symphony.
Makes easier the high registers and helps to focus the staccatto.More brilliant than E open Symphony backbore and with a sound with a lot of projection. Similar to V.Bach Backbore.
E open Symphony.
Backbore for all the symphonic repertoire. Powerful and big sound but without losing sound projection. If having problems with high registers or in focusing the staccatto, better choose the C medium Symphony backbore.
