1. Find maximum alternate picking speed, then choose a 3-string scale sequence where the 2nd note on the middle string is hammered (if ascending) or pulled-off (if descending) in a perfect 16th note so that the alternate picking remains in tact. For examples of this, see: https://guitarlessonsithaca.com/wp-content/uploads/2018/12/integrating-hammer-ons-and-pull-offs-with-alternate-picking.pdf

2. Do this all over the neck in your chosen key/scale

II. More Advanced

Choose any of the following:

1. Choose a specific rhythm from the following pdf and employ legato on the 16th notes. https://guitarlessonsithaca.com/wp-content/uploads/2023/03/combinations-of-one-or-two-16ths-with-eigths-quarters.pdf

If your lick crosses strings on a 16th note, you may have to use directional picking. https://guitarlessonsithaca.com/wp-content/uploads/2023/03/integrating-directional-picking-with-hammer-ons-pull-offs.pdf

2. Play a string of 8th notes at twice the tempo at which you can alternate pick over 1, 2, 3, or 4 bars, ending on the 1st beat of the next bar. For example, if your maximum alternate picking speed is 100, you would set the metronome to 200. For a 1-bar lick, you would choose a total of 9 notes, 8 of which are to be played within the bar & the 9th one is on the 1 of the next bar. Hold that note for that bar and repeat the exercise on bars 3 & 4. For a 4-bar lick, your total number of notes would be 33 (8 notes x 4 bars = 32 plus the 1st beat of the next bar.)
