Here's your target performance
Be a good pupil and work through the tapping drills conscientiously!
Learn to read the beat maps - they teach you to think effectively about rhythmic challenges.
Here's the Line Three phrase pattern - the basic off-the-beat rhythm.
Now play a hands-crossed version 'loco' - in position, using the same keys but hands crossed.
You immediately notice something different: one of the left hand intervals is played 'staggered' - bottom-top.
Work out what the three tapping patterns will be - Line One, Phrase One; Line One, Phrase Two; and Line Three phrases.
