The 7-string guitar’s range in notes and hertz
| Sounding | Written | Frequency | |
|---|---|---|---|
| Practical low | B1 | B2 | 61.74 Hz |
| Practical high | C♯6 | C♯7 | 1108.7 Hz |
| Extreme high | E6 | E7 | 1318.5 Hz |
A seven-string is almost always an electric, so the top is 21 to 24 frets above the high E. Dropping the low B to A moves the bottom down a tone.
Written and sounding pitch
The 7-string guitar is a transposing instrument: it sounds an octave lower than written. So the range on its part is B2–C♯7, while the notes you hear are B1–C♯6. The transposing-instrument tuner reads out the written note as you play.
