Many new piano students adopt crutches that boost them along very quickly for the first few weeks. But once the student has reached a certain point, these crutches hinder any progress. Note naming can be one of these. Since everyone is familiar with the alphabet, memorizing which keys on the piano correspond to which letter is fairly easy. And for beginner pieces, this works well. CCGGAAG (Twinkle) is easier for a person to read than some arbitrary symbols they’ve only recently been introduced to. But in the work below, someone took this to an extreme that is helpful to no one. Each of the notes in the picture indicates how long it should be held and exactly where on the piano it should be played. Letters convey a fraction of that information.
