This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4), tuned to 440 Hz (referred to as A440). [1] [2] Every octave is made of twelve steps called semitones.
Among alternative tunings for the guitar, an open G tuning is an open tuning that features the G-major chord; its open notes are selected from the notes of a G-major chord, such as the G-major triad (G,B,D). For example, a popular open-G tuning is D–G–D–G–B–D (low to high). An open-G tuning allows a G-major chord to be strummed on all ...
One can have more frets on a guitar (or keys on a piano) to handle both As, 9:8 with respect to G and 10:9 with respect to G so that A→C can be played as 6:5 while A→D can still be played as 3:2. 9:8 and 10:9 are less than 1 / 53 of an octave apart, so mechanical and performance considerations have made this approach extremely rare.
A man tuning an upright piano. Piano tuning is the process of adjusting the tension of the strings of an acoustic piano so that the musical intervals between strings are in tune. The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches. Fine piano tuning requires an assessment of the ...
Standard aka "Argentine tuning" or "G 6 tuning", one fourth lower than the charango. Very similar in appearance to the charango, but slightly larger. Charango, Ranka: 11 strings 5 courses.

Key coloration is the difference between the intervals of different keys in a single non-equal tempered tuning, and the overall sound and "feel" of the key created by the tuning of its intervals. Historical irregular musical temperaments usually have the narrowest fifths between the diatonic notes ("naturals") producing purer thirds , and wider ...
This leads to G ♯ and A ♭ being different pitches; G ♯ is, in fact 41 cents (41% of a semitone) lower in pitch. The difference is the interval called the enharmonic diesis, or a frequency ratio of 128 / 125 . On a piano tuned in equal temperament, both G ♯ and A ♭ are played by striking the same key, so both have a frequency
In open-G tuning (G,G,D,G,B,D), the 3 (B) of the open-G major-triad is on string 2. If we barre or use a slide to play the IV chord (C) at fret 5, the 3 of that chord (E) is still on string 2 ... as it will be when we slide up to the V chord, or the bVII chord, or the octave.
