D/F#
Consider a basic D chord and the standard alternating bass line for this chord which alternates to the 3rd string. Using the 3rd string as a bass note restricts the right hand fingers to the 2nd and 1st strings only (first position). To overcome this problem use an alternative fingering for the D chord such as the D/F# chord (D chord with an F bass note). Using this chord enables the right hand to use the 6th and 4th strings as bass notes thus allowing the right hand fingers to play the 3rd and 2nd strings. Study the adjacent diagram. Note that the F# bass note is played with the left hand thumb.
Shown next are the six patterns studied so far in the second position.
