Had I written this exercise I would have prefaced thusly. (Accountability)This is an excercise based on all the major/minor chords in all inversions, plus Dim 7th. Do not use damper pedal! At first...may use it later with the blocked chords..to practice pedal technique.By practicing this exercise you can learn to play blocked chords evenly and distinctly.You can also develop an awareness of the keyboard so that you will feel more secure in playing chords and be able to find the chords without looking at your hands..a necessity in sight reading! This is a Multi Task exercise in that you will be not only playing blocked chords but then you will play them all in an arrpegiated pattern, and then in broken chord pattern..so you will be developing facility in blocked chords, arrpegiated chords and broken chords.You will want to practice slowly at first, making sure to play each chord solidly. You should set the metronome at 60 or even slower....Common Time. (4/4) Likewise in the arrpegiated chords..pay close attention to each note in the chord..strive to play each evenly and with equal volume..all the way to bottom of key. Only speed up when you have this skill under wraps. You might notice that your 4th finger in the left hand needs strengtheningOne thing the exercise does is make you aware of where you are with finger "independence."This exercise will enable you to play a variety (solid, broken, and arrpegiated) of chords solidly and securely, in all keys.I'm sure I left out some of the other benefits.....just wanted to give an example of what I meant by accountability when an author/musician wirtes an exercise.
