Tuning your banjo with a piano ensures precise pitch matching. Start by identifying the banjo’s standard tuning (G-D-G-B-D) and locate these notes on a piano. Play the low G on the piano (third white key from the left) and adjust your banjo’s fifth string to match it. Then, proceed with D (fourth string), G (third string), B (second string), and D (first string), using the corresponding piano keys. Fine-tune by listening for clarity and harmony between the banjo and piano. Regular tuning maintains sound quality, ensuring your banjo stays in perfect pitch for seamless playing.
