The bluegrass mandolin instrumental “New Camptown Races” comes from mandolinist Frank Wakefield. It’s in the key of Bb, an unusual key for a mandolin tune, so Sharon starts by reminding you of the Bb major scale in Bb in open position, where much of the tune is played. The form of the tune is a little unusual too, with two A parts that are 16 measures long, and an eight-bar B part that is played only once, followed by the last half of the A part. Sharon walks you through the A part of “New Camptown Races” in this video.
