Trying to learn a piece by separating the "notes" from "refinement and "artistry" leads to learning the work incorrectly in terms of setting up baf habit mistakes in interpretation that are more difficult if not impossible to "inlearn " later on, it simply creates more work and extends the amount of time one ultimately needs to devote to the work since there will essentially be a need re learn parts previously covered
