    • Temperament (Mus) A system of compromises in the tuning of organs, pianofortes, and the like, whereby the tones generated with the vibrations of a ground tone are mutually modified and in part canceled, until their number reduced to the actual practicable scale of twelve tones to the octave. This scale, although in so far artificial, is yet closely suggestive of its origin in nature, and this system of tuning, although not mathematically true, yet satisfies the ear, while it has the convenience that the same twelve fixed tones answer for every key or scale, C♯ becoming identical with D♭, and so on.
    • Temperament Condition with regard to heat or cold; temperature. "Bodies are denominated “hot” and “cold” in proportion to the present temperament of that part of our body to which they are applied."
    • Temperament Due mixture of qualities; a condition brought about by mutual compromises or concessions. "However, I forejudge not any probable expedient, any temperament that can be found in things of this nature, so disputable on their side."
    • Temperament Internal constitution; state with respect to the relative proportion of different qualities, or constituent parts. "The common law . . . has reduced the kingdom to its just state and temperament ."
    • Temperament The act of tempering or modifying; adjustment, as of clashing rules, interests, passions, or the like; also, the means by which such adjustment is effected. "Wholesome temperaments of the rashness of popular assemblies."
    • Temperament (Physiol) The peculiar physical and mental character of an individual, in olden times erroneously supposed to be due to individual variation in the relations and proportions of the constituent parts of the body, especially of the fluids, as the bile, blood, lymph, etc. Hence the phrases, bilious or choleric temperament, sanguine temperament, etc., implying a predominance of one of these fluids and a corresponding influence on the temperament.

    • n temperament In music, the principle or system of tuning in accordance with which the tones of an instrument of fixed intonation are tuned, or those of the voice or of an instrument of free intonation are modulated in a given case. The relative pitch of the tones of an ideal scale may be fixed with mathematical precision. An instrument tuned so as to produce such a scale, or a voice or instrument using the intervals of such a scale, is said to be tuned or modulated in pure or just temperament. So long as these tones only-are used, no further adjustment is necessary. But if modulation be attempted, so that some other tone than the original one becomes the key-note, one or more intercalary tones are required, and the relative pitch of some of the original tones has to be altered. To fit an instrument for varied modulations, therefore, either a large number of separate tones must be provided for, or the pitch of some of them must be slightly modified, so that a single tone may-serve equally well for either of two or more tones whose pitches are theoretically different. This subject is necessarily of great practical importance in the construction of keyboard-instruments, like the pianoforte and the organ. Until comparatively recently such instruments were tuned in mean-tone or mesotonic temperament, so called because based on the use of a standard whole step or mean tone, which is an interval half-way between a greater and a less major second (see second, step, and tone). This standard was applied to the tuning of twelve digitals to the octave—namely, C, C♯, D, E♭ E, F, F♯, G, G♯, A, B♭, and B; and provided for harmonious effects only in the keys (tonalities) of C, D, F, G, A, and B♭ major, and of D, G, and A minor. Other tonalities presented an intolerable deviation from pure temperament, which was called the “wolf.” As the demand for greater freedom of modulation increased, various plans were tried for using more than twelve digitals to the octave, or for distributing the “wolf” more equally. The result of the latter effort is the system of equal or even temperament, first advocated by J. S. Bach early in the eighteenth century, though not universally adopted until the middle of the nineteenth century, in which the standard interval is the mean semitone—that is, the twelfth part of an octave. This distributes the “wolf” among all the tones of the instrument, so that the only intervals exactly true are octaves. Modulation, therefore, is made equally free in all directions: but, on the other hand, all chords are more or less out of tune. The benefits of the system in the way of providing a simple keyboard for music in many tonalities are largely counterbalanced by the constant deterioration of the sense of pure intonation on the part of those who use instruments tuned in this compromise temperament. This unmistakable disadvantage, reinforced by the fact that keyboard-instruments are much used in conjunction with the voice and with instruments of free intonation, like the violin, in which a just temperament is to be expected, has led to many new experiments with keyboards of more than twelve digitals to the octave, but without any result suitable for general adoption. Temperaments are sometimes known by various technical names, usually designating the interval chosen as a unit of measurement, such as commatic, schistic, etc.
