This product was for my 10-year old granddaughter who got a bass guitar for Christmas. After only viewing it for an hour, she already can play chords on the guitar and knows finger placement for 6 others. She will get formal lessons, but I think this is an opportunity for her to continue to be motivated at home. She has played the Viola for one year and the clarinet for 2 years. She is thrilled with the bass guitar -- all she wanted for Christmas!
