Dominant seventh arpeggio
Here are some of the standard fingering patterns for playing dominant seventh chord arpeggio. As usual, the root note is emphasized. The patterns are not named because they generally span more than one type of chord pattern.
Some of the patterns are very awkward. You'll also see some overlap in the patterns, which is more typical on these patterns where is a large stretch to reach the next note.
The same chords and patterns are shown in both a vertical and a horizontal display because some people have trouble with one form or the other.
Starting on the chord's root
Starting on the chord's third
Starting on the chord's fifth
Starting on the chord's seventh
Using the patterns
The notes in these patterns are a subset of the ninth chord patterns — one note is removed. Because some of the notes have larger intervals between them, the patterns will overlap more than one of the standard pentatonic patterns.
Once you understand how to build the 1-3-5-7 of the chord and learn a few of the patterns, you'll see how they interconnect. One example is the third pattern that starts on the chord's 5 note. It covers part of the both the patterns before and after it. You can always move to another pattern when it's convenient or to reach a starting point for a different pattern, such as a minor pentatonic.
