There are solutions that have been tried and found to work very well. The American shape note system made 3 and 4 part harmony singing something the whole congregation could take part in, rather than just an elite choir. Lars Roverud's digit notation system (and the system to teach it) did a similar thing for singing in Scandinavia. They fell out of favour not because they didn't work, but because professional musicians and teachers saw it as a crutch instead of a system in its own right, and kept pushing for graduating to "real" notation.

Shape note notation doesn't, and doesn't try to, replace traditional notation, which is what Clairnote is trying to do.
