Hi @shanti.garlock
A couple of tips to help you memorise tunes is first off knowing the fundamentals inside out, The roll patterns, licks and melodic runs. They provide you with the structure to build signature phrases that are the building blocks, the framework of every tune.
By working your way through @BanjoBen 's learning pathway and carefully studying what Ben is teaching, these fundamentals will soon become very familiar to you. Eventually with practice they become second nature, like riding a bike, breaking an egg, making a cup of coffee. These are every days tasks we do without having to think about them, we just know how.
Listen I mean really LISTEN to the tune over and over again. Hang on to every note and eventually you will be predicting which note or musical phrase comes next.
Finding the time to sit down and listen to tunes can be a challenge in our busy lives but @Mark_Rocka has found a solution and I think its a great tip for everyone learning a musical instrument, Mark downloads Ben’s MP3 files and listens to them as he drives around in his car. Now why didn’t I think about this ten years ago when I started out.
Another great tip is to learn the Kick off’s and Ending phrases. Ben has several lessons on these topics. Learning the Kick Offs leads the way into a tune, Once upon a time, They all lived happily ever after etc…
Most of Earl Scruggs tunes has at least one or two key signature licks, identifiers within the tune that helps lead the listeners ears and tells the story. Foggy Mountain Breakdown, Shuckin the Corn, Sally Goodin
Adding these to your library of fundamental licks will enhance your ability to memorise tunes even more. As your LISTENING try to identify and predict when and where one of these Key Signature Phrases fits into a tune. I guarantee it will help you remember when you come to sit down to play.
Finally learn to relax, accept the fact that there will be times you will mess up. Don’t allow yourself to become frustrated. If you find you are getting stuck on a lick or musical phrase, slow it right down, break it down into smaller more manageable pieces and work on it till it becomes second nature.
Have Fun Happy Picking
