As I was formerly in Northern VA, in the suburbs of Washington DC, there were many who charged $100 / hour, and more if they came to your home. As I don't know all the tutors in that area, I'm not sayin' all charged that much, and I'm not sayin' others than me charged any less. Some were working instrumental music teachers in the school systems and others were performers in the reknown local symphonies, orchestras and military bands. It was one from the Navy band through a local music store that tutored my daughter about 30 years ago and then the hourly rate charged was $25.00 ... and it was worth every dollar and coin thereof. I take the attitude even now that if I were to engage a different tutor every six months for as long as I can play the remainder of my life, I would learn something from every one of them. There's a story about my attitude as when I first became disabled some may want me to tell, but I'll hold off until there is a request that I tell it ... although it is in a different art than music.
