Crossover licks are easy to play when you look at them from another
point of view. I use the right hand position to change crossover licks.
The examples below will show you this easier than it can be explained
We first need to establish the different crossovers that I use
1. Two finger to two finger
2. Two finger to three finger
3. Three finger to two finger
4. Three finger to three finger
The right hand picks an alternate in one position and then skips
to another. The last example shows two forward rolls in position 8
and position 5. The position is where your thumb is located.
Above the forward rolls are seen in six different positions. To make
a crossover lick you can do variations of the positions. It's your
choice whether to play a two or three finger crossover movement. Either
way will work.
