I worked with my daughter on learning her letters with sounds, books, tiles, refrigerator magnets, ect from age 1 to 5 and she could not retain the information. I could not get her to learn any letter but A, then the next day she could do half of them and then the next day or an hour later she couldn't say any of them. When she got to Kindergarten she took off with reading and went from nothing to a 5th grade level in 2 years.
Now she has been taking piano for 3 years and still randomly cannot remember the letter names. Her piano teacher calls it a "knowledge dump". She couldn't even find middle C one day.
Has anyone experienced this? She is Gifted and Talented and a very good artist. She wants to quit music because of the frustration of reading the note names. I have a degree in music and she begged for years to play and I hate that she has frustration. The school tested her and found no evidence of dyslexia.
