Orchestral tuning is E A D G, with the strings a fourth apart. Solo strings are tuned a whole step higher, to F♯ B E A.
The double bass is also called the upright bass, contrabass or string bass. The tuning is the same.

Frequently asked questions
What are the double bass string notes?
Orchestral tuning is E1, A1, D2 and G2, the same notes as a bass guitar. Solo tuning raises every string a whole step, to F♯ B E A.
The tuner struggles with my low E. Why?
Laptop and phone microphones can barely hear 41 Hz. Play a harmonic instead (touch the string lightly at its halfway point) and lock the string in Manual mode.
