We hope that these recordings are a good reference. There is always some danger of students learning their etudes by rote. Rote gets you close, but a good musician/teacher/adjudicator can hear if someone has not taken the time to understand the music. Be sure to take these etudes apart. Know the scales involved. Understand the basic pulse of the meter and the rhythms that fit in between. Find the phrases and you will have a good start on where to breathe.
There's a lot more to being a good musician than understanding the fundamentals. A good teacher can set you on the right track to use those fundamentals as building blocks to creating wonderful phrases.
