A trill is performed by quickly hammering on and pulling off two notes. It’s usually represented by a “tr” and a squiggle line like seen for a vibrato. In the example below, you can see a trill in tablature. Place your 1st finger on the note on the 7th fret and use your 3rd finger to rapidly hammer on and pull off on the 9th fret-which is in parenthesis.
