Long tones on F#
Now it’s time to add our first fretted note, the F#; most folks play it with their middle finger on the D string. Hit some long tones on this note to make sure that you can play it cleanly. I recommend taking your finger off the note while you are listening to the tone. That way you can practice moving your finger into the note with every dictation.
Concentrate on playing the sound that you hear. You want to be exact.
