ABC Fingering Chart ————————————————————————This chart shows the chord fingerings recognized by the QY20 ABC system. 3-, 4-, and 5-note
fingerings can be used, depending on the inversion and tensions required. In the fingerings “1” is the root,
“3” is the 3rd, “7” is the seventh, and so on. The “Comments” column indicates inversions that should be
avoided because they produce a different chord.
