The tuner is already set to Drop C: play each string and get it green. Below, which strings change from standard tuning and their frequencies.
Tap “Turn on microphone” and play a note.
Sound is analysed on your device. Nothing is recorded or sent anywhere.
Dropping several strings lowers the total tension and the neck shifts a little: go round once more when you finish.
Like Drop D, a whole step lower: one-finger power chords in a very low register. Widely used in metal.

Not for one or two semitones down. If you go lower, slightly heavier strings keep them from going slack and buzzing.
