The viola is a very special instrument that attracts fewer players, but those who choose to play viola tend to develop a deep love for the instrument and its unique tone quality. I remember reading a book from the public library when I was in high school that consisted of interviews was well-known string players. The author of the book made the comment that each violist he interviewed stated that violists share a particular type of personality, whereas violinists and cellists covered a wider range of personalities.
If you are drawn to play the viola, the go for it! You’ll love playing this most unique instrument . . .
