This fingering sequence is the fingering for twenty-three different scales - that is, if you count all the forms of the minor you will be playing. It is critical that you learn this as a fingering combination rather than just what the right hand is doing and what the left hand is doing. I suggest that you spend a substantial amount of time working the two octave fingering printed on page 98 of your text on a "flat surface." You don't want to use the keyboard as a crutch - "third finger in RH goes on F#" - it is the same fingering for every one of these over 20 scales. You only have to learn it once! ! !
In the exercises with the E major scale I will call off the fingerings for both hands, left hand first. It is an excellent way to think about how the hands work together. I encourage you to do this in your practice and particularly when you are simply "playing" the fingerings on a flat surface. I have chosen E major because it is the easiest to play of these five major scales. It is totally symmetrical - white key, two blacks, two whites, two blacks and a white key to end. I actually think C major is one of the hardest scales to play. All white keys give you no points of reference.
The four exercises in the keys of G, D, A and E are item 2 from page 98 written out so you can look at the pitches and think about the fingerings.
