Post by A totally insignificant person.I read somewhere that you should never play the black keys with your
thumbs.
Why?
OK. First "never" is an extreme genralization. I have seen
music where it's impossible to play a passage properly without a thumb
on a black key. There's one in Chopin's Sonnata in B flat minor, for
instance.
Thumbs are generally shorter that fingers and can reach the white
keys easier. Fingering is all about making the notes easy to play, and
using the correct fingers to advantage in accenting the notes. The
thumb is a "clunker" and has greater strength than the other fingers.
the pinky, (5), is usually weak. So 2,3,and 4 can be thought of as the
"singing fingers." They make the music "sing" when you're looking for a
good sound. There are tradoffs between these two objectives. Where
convenient, it's great to use the thumb on the downbeat or an accented
note.
Then finger exercises help even out the "touch" of the different
fingers to give the pianist more options in fingering. A good piano
teacher can stand well away from a student playing the piano and correct
the fingering without even looking at the student. My teacher was
William Stevens, who was a concert pianist and used to do USO shows with
Bob Hope. I was playing something, I forget what, and he called out
from the other side of the room, "NO! Put your 4 on B flat!" I said,
"How did you know that?" and he said, "I heard it!" There was a little
break in the rhythm because I had used the wrong fingering. Later he
told me that he couldn't really tell me what fingering I had used, but
he knew it wasn't the right fingering. He was playing the piece along
with me in his mind.
