This is the first time for you to see a dotted quater note.
You are opening another new door ! 🙂
I’d like you to know the meaning of the dot, but for now, I rather you to just feel and play the rhythm, since you are still young: will be a 3rd grader ! 🙂
For a dotted quater note, you can feel 3 eighth notes,
you can feel the quater note beat and play the eighth note after the click of the metronome.
You can practice the same rhythm on other open strings as well, like on D string, E string, and G string.

Don’t forget to practice no.87 correctly which is a preparation exercise for no.88.
There are two tempi recorded; quater note = 67 and 80. You can pick one which help you to play comfortably.
Look forward to listening a wonderful playing next time!
