Note: these are the same basic requirements as for all elementary jamming.
You must be able to tune your instrument accurately, in a minute or two, with an electronic tuner.
You must be able to smoothly change on your instrument, between the chords G, C, D, and A. Fiddles and basses need to play the single notes that go with each chord.
To be sure you meet these requirements: Pete’s video Bluegrass Slow Jam for the Total Beginner presents 17 songs using only G, C, D, and A, at minimum bluegrass tempos. Learn to follow guitar chords, shown magnified on screen. G, C, D, and A are shown on all six instruments. Order from the Jam Store. Playing along with this video will build your confidence!
If you are having problems with either of these skills despite using the item above, please contact your teacher, whose email address is on the page advertising your class.
