There are two ways to play the F(h). The first is with your first finger on the third fret of the 1st string (that should be easy to remember!). This is the fingering most folks use to start playing. You can also use the middle finger on the sixth fret of the 2nd string.
Remember, scaffolding is available if you need help.
Don’t forget to do Musical Gym and work your way up to 120bpm.
