Many new players dive into learning songs without understanding the musical foundations behind them. Focus on understanding basic chord construction and scales. You could start by learning how G, C, and D chords relate to each other – these are the I, IV, and V chords in G major, a common banjo key. It’s easy to focus on just hitting the right notes, but in bluegrass, old-time, or any banjo style, timing is everything. A beginner can learn a tune note for note, but still sound “off” if they’ve not got a strong sense of rhythm.
