Nothing in the way.
OK, what do I mean?
First, Nothing in the way:
What gets in the way, distracting the listener from the music?
- Poor tone
- Faulty intonation
- Bad rhythm
- Weak ensemble blend
You can have good tone, be in tune, play good rhythms in time but still have nothing to say musically!
In other words, "Nice stage but where's the play?"
Something to say. Nothing in the way.
