I am going to be sure to let you all know it is quite ok to ask questions.
That is the Tip of the Day.
Reach out and ask. Ask about Chords, melody everything.
If you see another mandolin player that is playing some cool stuff you would like to learn, just go up and ask. I am certain they will assist in any way possible.
If there is a guitar player and he is playing rhythm (he is your best friend) ask about the chords and the changes.
Do not be shy..just ask while you have the chance.
Take the info back and digest it and play with it.
Fun, Fun and even more fun!
ps. You can ask me anytime
