My instructor, Tamara Hammond is excellent. She focuses on the fundamentals and is able to communicate the 'intangible necessities and blessings' of classical guitar. To learn more about Tarama, click on her photo. I played the trumpet throughout elementary, middle and high school. While it's great to play any instrument, it just doesn't work to pull out the trumpet at a gathering and impress everybody with the solo trumpet section from 'In The Mood'.
Classical guitar is versatile, entertaining and extremely beautiful instrument.
There are, of course, many, many more.
