Here is one of million piano arrangements of Ed Sheeran's "Perfect" that I've chosen for learning. And now I'm stuck trying to choose between two fingerings for left-hand line in this part (marked with red on the picture).
- 5 for bass note and 531 for chord
- or 5 for bass note and 421 for chord
Both of them comfortable and easy enought for me, but I consider this piece not just as piece, but also as exercise to master different left-hand lines (chords, arpeggio, bass/chord, and so on), so I'm trying to choose the fingering that is more common for such lines to master them for better skills development.
Seems like 5-421 is better for fast passages (because hand jump between bass and chord is shorter), but 5-531 seems a bit more comfortable for part marked with green on pictire (like 5-531-521-531), and I'm not sure that mixing theese fingering schemes is a good idea in learning-purposes terms.
So, what do you think will be better, looking from this prospective?
Context: I'm a 3-month-practice piano beginner, but with well-developeg fingers coordination (20 years of 10-fingers blind typing on computer keyboard, advanced-amateur guitar 15 years experience and so on). For now I've learned 6 piano pieces with about the same level of difficulty that this one is.
