Just looking for any advice in a time of extreme frustration. I'm trying to fine tune Hummel, and I have consistant trouble with that last slurred line. I CAN play it, but it's not consistant, and I often find myself missing the attack, or lacking enough air to support the trill at the end. I realize this is vague, it's more fuming than anything, but any ideas as to whether I need to work on air support, or perhaps I'm just fatigued by the time I get there, or anything else, would be very helpful. Thanks.
