How to tune a 5 string bass online
Tap Turn on and allow microphone access so the tuner can hear your bass. Pluck one open string and let it ring longer than you would on a guitar, since low notes take a moment to settle. The tuner shows the detected note and whether you are flat or sharp. Turn the tuning key in small steps, then pluck again to recheck. Work through the strings one at a time until each note centers on the target. When finished, do a quick second pass to confirm the earlier strings stayed in tune.

Standard 5 string bass tuning and note targets
Most 5-string basses add a low B below standard tuning, giving B E A D G from low to high. Use the note list on the page as your target and tune from the lowest string upward for a consistent reference. Aim for a stable reading on the low B before moving on, since it can influence how the instrument feels and responds. If you use a different setup, start by matching the closest standard notes, then adjust each string to your preferred pitches. Keeping your targets clear helps the tuner lock in faster and keeps your tuning routine simple.
