Yes. People like you and me, with good musical memories, usually are lousy
at remembering the words, or the titles. I have been known to whistle a
common tune for days without being able to come up with the name, and when I
finally find someone who knows its name, it is a very common tune that I
have known since grammar school some 65 years ago. But computers have a
difficult time with music. Try to find a good program (for example) that can
import a photo of a score, in JPG or PDF format, into a music notation
program, or a MIDI file. The ones that I have tried are very poor at it, and
require so mush clean-up work that you are almost better off entering the
music note by note yourself. Especially if you are trying to enter piano
scores with multiple voicing's. There are programs that will generate scores
directly from the played music, but these tend to over exactly notate the
timing, and give you a score full of dotted 32nd notes and the like, in an
attempt to get the timing right.....They make for a very messy document that
is virtually impossible to read.
