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 ...
The so-called "Pythagorean tuning" was used by musicians up to the beginning of the 16th century. "The Pythagorean system would appear to be ideal because of the purity of the fifths, but some consider other intervals, particularly the major third, to be so badly out of tune that major chords [may be considered] a dissonance." [2]
Piano tuning is a compromise—both in terms of choosing a temperament to minimize out-of-tuneness in the intervals and chords that will be played, and in terms of dealing with inharmonicity. For more information, see Piano acoustics and Piano tuning.
The pitches of open strings on a violin. Play ⓘ. In music, the term open string refers to the fundamental note of the unstopped, full string.. The strings of a guitar are normally tuned to fourths (excepting the G and B strings in standard tuning, which are tuned to a third), as are the strings of the bass guitar and double bass.
The longer a piano remains out of tune, the more time and effort it will take for a technician to restore it to proper pitch. When a piano is only slightly out of tune, it loses the glowing tonal quality characteristic of a freshly tuned piano , especially because each note in the middle and upper range is sounded by more than one string, and ...
And the problem of how to tune complex chords such as C 6 add 9 (C→E→G→A→D), in typical 5 limit just intonation, is left unresolved (for instance, A could be 4:3 below D (making it 9:8, if G is 1) or 4:3 above E (making it 10:9, if G is 1) but not both at the same time, so one of the fourths in the chord will have to be an out-of-tune ...
Composers may use chord substitutions when they are basing a new jazz tune on an existing chord progression from an old jazz standard or a song from a musical; arrangers for a big band or jazz orchestra may use chord substitutions in their arrangement of a tune, to add harmonic interest or give a different "feel" to a song; and instrumentalists ...
Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine (acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell , or activating an electronic circuit (synthesizer, digital piano, electronic keyboard).
