五級鋼琴應該彈D 咩書?

可以試試 Bach French Suite (Baroque)
Sonatina Album (Classical)
Chopin Marzuka (Romantic)
Alan Haughton, Rhythm and Rag (20th Century)

Guide line 的話, 可以參考 Exam syllabus, 例如 A:1 Haydn Vivace assai: No.11 from 12 petites pieces, 你可以用 Haydn's 12 petites pieces 做平時彈的 music.

希望幫到你.

masterpiece is a good book to learn. "masterpiece" is the name of book
