Reentrant tuning sets certain instruments apart because the strings don’t ascend or descend in pitch order. In the modern era, guitars influence many instruments, so most of them follow a sequential tuning. However, centuries ago, instruments with reentrant tuning were common and left us a rich repertoire of music.
The Venezuelan Cuatro is a small four‑stringed instrument with a standard tuning of A–D–F#–B. The B string is tuned an octave lower than expected, creating the reentrant effect that gives the Cuatro its lively, ringing tone.
