Ben - I am really tired, been on the go (working) for 16 hours, excuse me if I am unclear, and don't address this on a note-by-note case.

I have listened to it. Do you hear your last note being especially sharp? (It sounds like a trumpet's D to me).

Do you hear that some of this is actually pretty well in tune, but other bits aren't? That D is notoriously sharp!

Consider using triggers/lip more. I think you play reasonably near pitch, but it is so hard to hear whether you are relaxed without seeing you. I do know that there are notes that are a bit wild that are correctable with trigger or lip.

Don't be too hard on yourself - the mic is grim, but it shows up time issues - your time feel is somewhat laboured and "marchy" for a jazz tune. Relax, feel those off beats as something equating to either 2 + 1 (crotchet quaver triplet) or 3 + 2 (dotted crotchet, crotchet quintuplet). What I am trying to say is that "swing" can be felt, but it is hard to notate. The triplet is going to be what you feel easiest, but it quite easily becomes 3 + 1 (dotted crotchet, semiquaver), IE brass band-y.

The answer to time feel is not maths, it is to listen to the masters of time: Wynton Marsalis, Woody Shaw, Freddie Hubbard, Arturo Sandoval, James Morrison, Byron Stripling, Lew Soloff, Tom Harrell!

Metronome work is good as well.

Anyway, bed is required

Good on you posting again!!

Mike

As far as playing with ease goes, my first port of call is always the breath. Make sure its a really good full yet relaxed one. Thereafter, the exhale needs to be equally relaxed and free from tension. In essence, you are trying to take a big breath, empty your lungs fully or partially and then take another one. Sounds simple enough but problems start when we try and keep hold of the air or conserve. If you can't get through a phrase take a bigger breath.

Kristian Steenstrup does a lot of work away from the instrument blowing the air onto the back of the hand so that you can monitor the quality of the airstream and to get away from any instrument related apprehension. Once that is working well then you can try and copy that airflow with the instrument. I was quite shocked by the difference in feel between the 2 when I started doing it. The idea of thick air truck a real chord with me.

Once that is working well you may find that your tuning has altered and a slide position rethink may be in order.
