Guitar tunings almost always refers to the pitch of the open ("unfretted") string, though some tunings may only realistically be attained by the use of a capo on an unmodified instrument. Like many other stringed instruments, guitar tunings can be easily modified. When speaking of a tuning such as standard tuning, EADGBE refers to the pitches of the strings from lowest pitch (low E) to highest (high E).

Standard tuning is by far the most popular tuning on a 6-string guitar. It consists of the following notes. String Note Frequency Scientific pitch notation 1 (Highest) e' 329.63 Hz E4 2 b 246.94 Hz B3 3 g 196.00 Hz G3 4 d 146.83 Hz D3 5 A 110.00 Hz A2 6 (Lowest) E 82.41 Hz E2 The pitches referred to above are referenced standard pitch (a' = 440.0 Hz.). In some regions of Europe, especially Germany, Serbia and Poland, and in Russia and Ukraine, where classical musicians use the German system, the B natural is indicated with the letter H: in music notation, H is B♮ (B natural) and B is B♭ (B flat). The guitar, as conventionally fretted, is an equal tempered instrument.
