Hammer-ons on the pentatonic scale
STOP! Hammer-on time!
A hammer-on is a way you play a certain note on a guitar. You perform a hammer-on by sharply bringing down a fretting finger on a string so that a note sounds without picking it with your picking hand. The opposite of a hammer-on is a pull-off and you'll play it (if you haven't already) in another exercise, so don't worry.
The important part of the hammer-on is that the note sounds loud and clear so this is what you'll be practicing - and making it sound cool by playing it on the pentatonic scale.
You will play two notes per string exclusively and you will always pick the first note with a downstroke and then perform a hammer-on on the second note. Remember to always position your fingers in the 1-2-3-4 position (one fret one finger) so your fretting hand isn't flying all over the guitar but stays as still as possible.
