I don't believe that musicianship is instrument specific. Musicianship goes beyond a short list of technical skills, dynamics or use of tone color. It rises from the performer's inner understanding of the music and is applied through his/her technical capacity using selected articulation, dynamics, tone color, etc.
I've always thought of musicianship in terms of the application of stylistic and interpretive skill but this article below cites uses singing--and more specifically, the ability to hear the music you play (or sing) before you play it. It may seem a bit off topic in regards to your request but after thinking about it, I think the author is spot on. Our ability to sing the music we play and eventually hear it in our head, forms the basis of our musicianship. It allows the music to be created within us, in our head and heart, before it gets to our fingers.

It's something to think about....
So much music, so little time.
