The songs you can play are referred to as your “repertoire”; songs that you know beginning to end and can perform without looking at the sheet music or tablature. Ideally, a couple of these songs should be ‘solo’ pieces: an instrumental or an accompaniment you sing to. It is good to know a couple of easy songs that you can quickly show other musicians. These will get you invited to the next jam session!
Keep working on new tunes and periodically cycle through your familiar tunes, keeping them fresh. A decent guitar repertoire avoids that ‘deer in the headlights’ feeling when faced with the inevitable request from family or friends, “Play me something!”
