Hi Shigeki Adachi,
You've really excelled yourself with this creation. The composition takes musical invention to whole new heights! I agree with floyd... this is one of the best 'instrumental + arrangement' that I've heard on here.
In ways that are uniquely Shigeki Adachi, you have skillfully captured the essence of Mozart. In addition, you have capitalised on those signature appogiaturas that are liberally sprinkled throughout Mozart's melodies.
Very impressive in every way!
Regards,
Noel
P.S. You've inspired me to try my hand at using BIAB to arrange something by Mozart.
