I am taking piano lessons, and my teacher has taught me the scales and chords/arpeggios for the keys of C, G, D, A, and E. So far, the fingerings for the chords of each key have been the same- fingers 1, 3, and 5 on each hand. For example, for a C chord:
Left hand: Right hand:
5 on C 1 on C
3 on E 3 on E
1 on G 5 on G
This seems natural to me, especially since I can play the 4-note or the 2-note of chords without adjusting where my hands are. However, the fingering for B was taught differently. For a B chord, I'm taught:
Left hand: Right hand:
5 on B 1 on B
3 on D# 2 on D#
2 on F# 3 on F#
As you can see, neither hand is 1-3-5 fingers, and the hands are different from each other. I would have thought that with 5-3-2 on the left hand, then the right hand would perhaps be 1-3-4.
My teacher is university-trained and has been playing/teaching her whole life, but she did not have a ready answer when I asked why the fingering for B was different that way, especially the right hand. She might come back with an answer during a later lesson (which is fine- I'm doing as taught even if I don't fully understand), but I was wondering:
Does anyone know why the fingering for B would be done this way?
Is there some advantage which I don't yet realize, some common note progressions that this facilitates, or some easier way to change to other common chords?
Edit: For example, I am thinking that the right hand 1-2-3 positioning would make some song melodies more difficult to play in the key of B (e.g., the "Ode to Joy"), and quite a few songs that I am familiar with use the notes 1 through 5 heavily in their melodies. If playing these in the key of B, maybe for these I would use a different positioning, but does the 1-2-3 positioning offer any benefits that I might not be seeing?
(Note: I realize that there are probably other ways that B is taught. I'm not trying to find a better or different way with this question. I am only trying to find out the reasoning for this particular fingering.)
