Inspired by all the learning to read threads here in General Instruction I've set out to learn how to read music. For myself the best thing I've found so far is the Clef reading section over at teoria.com: http://teoria.com/exercises/read.php
I set it up so that I'm reading bass clef, in groups of 4 notes at a time, answering using note names, for a period of five minutes, with 20 seconds to answer for each note. So far I'm getting better, with a 95% or better score, and I can recognize a D, F, low F, and high B by sight, but I'm still relying too much on Good Boys Do Fine Always, and All Cows Eat Grass, which is OK for now but in time I'll eventually have to abandon in favor of instant note recognition and identification.
I'm taking my time in learning how to read. After all, how long will it take a kindergartener to read War And Peace? At least 12 years! But do I need to get note recognition down first before moving to anything else.
