I realize that fingering is a complex topic. But are there any simple rules that a beginner can start with?
EDIT: This question was originally marked as a duplicate of this question I realize now that I can't position my hands solely based on the key of the song. But that doesn't tell me if there are other basic rules that can be used.
I can sight-read and play the chromatic harmonica fairly well. I want to start learning piano/keyboard. I know that if I worked my way through some beginner books, like Alfred's or Aaron's, I would eventually pick up tips on fingering. But I would much rather learn by just playing the tunes I can already sight-read on harmonica.
My main problem is that I have no clue where to place my fingers when I start to play. Let's assume we are talking only about the right hand for the melody.
Should I first find the lowest and highest notes in the first few measures. Then position my hand to be able to play most or all the notes without moving my hand. But what if there is a 6 or 7 note range? Do I position finger 1 (my thumb) over the next to lowest note because it's easier to stretch that finger than finger 5 (my pinky)? Or should I do something else entirely?
As some concrete examples, take these Beatles tunes:
I Saw Her Standing There. Key of C. The notes in the verses range from a lowest of C4 to a highest of F5b. In the first 6 measures, they range from G4 to C5.
When I'm Sixty Four. Key of Bb. The notes in the verses range from a lowest of B4b to a highest of D5. In the first 6 measures, they range from C4# to D5
