Click "Start Listening" and select a string to tune. Auto-detect is assist-only and works best when the string is already close to pitch.
Drop tunings lower the lowest string (and sometimes others) to create a heavier, darker sound. Drop D is the most popular: you lower the 6th string from E to D, making power chords playable with a single finger barre across the bottom two or three strings. This enables faster riff playing and gives you a deeper bass note for heavy palm-muted sections. Drop C, Drop B, and Drop A go even lower for extreme metal styles.

Tips for Drop tunings
Power chords become one-finger shapes across the bottom strings
Consider using slightly heavier gauge strings for better tension
Great for riff-heavy music and palm muting
Drop D only changes one string, so most chord shapes still work
String gauge tip
For drop tunings, consider using slightly heavier strings (.011-.052 or higher) to maintain good tension and prevent fret buzz on the lowered strings.
