Hello, i've recently had many arguements with my friends on which sax is harder to do altissimo and to double tongue on. I play bari and i can climb up to Altissimo Double F. I can also double tongue at 180. My friends said both these techniques are easier on Bari and i Said that Altissimo may be a bit easier, but Double tongueing is WAY more difficult due to the air support that is needed to sustain the Ka sound. But they think bari is overall the easiest sax to play and every technique is easier on it. Anyone have any verbal ammo for me to fight back with?
