What is a "vocal coach" and how does it differ or is specific in comparison to the vocal learning / training in general?
I worked as a vocal coach for 20 years, mainly working with actors and preparing them for musical theatre and auditions. I always made it clear that I was not a singing teacher. In other words, I never taught technique. Here are some examples of my input:
Where to breath in a song, finding the correct key for their range, presentation of the song: this often involved finding the character... where to look, when to move, how to stand, what to wear, which accent to adopt, editing the song for their auditions. I would play the accompaniment and mark the music for repeats, endings etc.
I always worked in conjunction with a singing teacher. A vocal coach needs to be a proficient musician and a decent piano accompanist, whereas a singing teacher is always, primarily a trained singer. http://www.learnjazzpianoonline.com
