Measurement

While tempo is described or indicated in many different ways, including with a range of words (e.g., "Slowly", "Adagio" and so on), it is typically measured in beats per minute (bpm or BPM). For example, a tempo of 60 beats per minute signifies one beat per second, while a tempo of 120 beats per minute is twice as rapid, signifying two beats every second. The

Instead of beats per minute, some 20th-century classical composers (e.g., Béla Bartók, Alberto Ginastera, and John Cage) specify the total playing time for a piece, from which the performer can derive tempo. With the advent of modern electronics, bpm became an extremely precise measure. Music sequencers use the bpm system to denote tempo.

Musical vocabulary

In classical music it is customary to describe the tempo of a piece by one or more words, most commonly in

, in addition to or instead of a metronome mark in beats per minute. Italian is typically used because it was the language of most composers during the time these descriptions became commonplace. Some well-known Italian tempo indications include "Allegro" (English “Cheerful”), "Andante" (“Walking-pace”) and "Presto" (“Quickly”). This practice developed during the 17th and 18th centuries, the baroque and classical periods. In the earlier Renaissance music, performers understood most music to flow at a tempo defined by the tactus (roughly the rate of the human heartbeat). The mensural

indicated which note value corresponded to the tactus. In the Baroque period, pieces would typically be given an indication, which might be a tempo marking (e.g. ''Allegro''), or the name of a dance (e.g. ''Allemande'' or ''Sarabande''), the latter being an indication both of tempo and of metre. Any musician of the time was expected to know how to interpret these markings based on custom and experience. In some cases, however, these markings were simply omitted. For example, the first movement of

wrote "In tempo d'un Menuetto" over the first movement of his Piano Sonata Op. 54, though that movement is not a minuet. Many tempo markings also indicate mood and expression. For example, ''presto'' and ''allegro'' both indicate a speedy execution (''presto'' being faster), but ''allegro'' also connotes joy (from its original meaning in Italian). ''Presto'', on the other hand, simply indicates speed. Additional Italian words also indicate tempo and mood. For example, the "agitato" in the ''Allegro agitato'' of the last movement of

Basic tempo markings

Here follows a list of common tempo markings. The beats per minute (bpm) values are very rough approximations for time. These terms have also been used inconsistently through time and in different geographical areas. One striking example is that ''Allegretto'' hastened as a tempo from the 18th to the 19th century: originally it was just above ''Andante'', instead of just below ''Allegro'' as it is now. As another example, a modern ''largo'' is slower than an ''adagio'', but in the Baroque period it was faster. From slowest to fastest: * ''Larghissimo'' – very, very slow (24 bpm and under) * ''Adagissimo'' – very slow (24-40 bpm) * ''Grave'' – very slow and solemn (25–45 bpm) * ''Largo'' – slow and broad (40–60 bpm) * ''Lento'' – slow (45–60 bpm) * ''Larghetto'' – rather slow and broad (60–66 bpm) * ''Adagio'' – slow with great expression (66–76 bpm) * ''Adagietto'' – slower than ''andante'' (72–76 bpm) or slightly faster than ''adagio'' (70–80 bpm) * ''Andante'' – at a walking pace, moderately slow (76–108 bpm) * ''Andantino'' – slightly faster than ''andante'' (although, in some cases, it can be taken to mean slightly slower than ''andante'') (80–108 bpm) * ''Marcia moderato'' – moderately, in the manner of a march (83–85 bpm) * ''Andante moderato'' – between ''andante'' and ''moderato'' (thus the name) (92–112 bpm) * ''Moderato'' – at a moderate speed (108–120 bpm) * ''Allegretto'' – by the mid-19th century, moderately fast (112–120 bpm); see paragraph above for earlier usage * ''Allegro moderato'' – close to, but not quite ''allegro'' (116–120 bpm) * ''Allegro'' – fast, quick, and bright (120–156 bpm) * ''Molto Allegro –'' fast (124–156 bpm) * ''Vivace'' – lively and fast (156–176 bpm) * ''Vivacissimo or Vivacissimamente'' – very fast and lively (172–176 bpm) * ''Allegrissimo'' or ''Allegro vivace'' – very fast and bright (172–176 bpm) * ''Presto'' – very fast (168–200 bpm) * ''Prestissimo'' – very, very fast (200 bpm and over) (At this tempo, cut common time is often used)

French tempo markings

Several composers have written markings in French, among them baroque composers François Couperin and Jean-Philippe Rameau as well as Claude Debussy, Olivier Messiaen, Maurice Ravel and Alexander Scriabin. Common tempo markings in French are: * ''Au mouvement'' – play the (first or main) tempo. * ''Grave'' – slowly and solemnly * ''Lent'' – slowly * ''Moins'' – less, as in ''Moins vite'' (less fast) * ''Modéré'' – at a moderate tempo * ''Vif'' – lively * ''Très'' – very, as in ''Très vif'' (very lively) * ''Vite'' – fast * ''Rapide'' – rapidly Erik Satie was known to write extensive tempo (and character) markings by defining them in a poetical and literal way, as in his Gnossiennes.


German tempo markings

would further elaborate on combined tempo and mood instructions in German. For example, the second movement of Mahler's Symphony No. 9 is marked ''Im Tempo eines gemächlichen Ländlers, etwas täppisch und sehr derb'', indicating a slowish folk-dance-like movement, with some awkwardness and much vulgarity in the execution. Mahler would also sometimes combine German tempo markings with traditional Italian markings, as in the first movement of his sixth symphony, marked ''Allegro energico, ma non troppo. Heftig, aber markig'' (Energetically quick, but not too much. Violent, but vigorous).

Terms for change in tempo

Composers may use expressive marks to adjust the tempo: * ''Accelerando'' – speeding up (abbreviation: ''accel.'') Opposite of Ritardando, it is an Italian term pronounced as ht-che-le-rahn-dawand is defined by gradually increasing the tempo until the next tempo mark is noted. It is either marked by a dashed line or simply its abbreviation. * ''Affrettando'' – speeding up with a suggestion of anxiety * ''Allargando'' – growing broader; decreasing tempo, usually near the end of a piece * ''Calando'' – going slower (and usually also softer) * ''Doppio movimento'' / ''doppio più mosso'' – double-speed * ''Doppio più lento'' – half-speed * ''Lentando'' – gradually slowing, and softer * ''Meno mosso'' – less movement; slower * ''Meno moto'' – less motion * ''Più mosso'' – more movement; faster * ''Mosso'' – movement, more lively; quicker, much like ''più mosso'', but not as extreme * ''Precipitando'' – hurrying; going faster/forward * ''Rallentando'' – a gradual slowing down (abbreviation: ''rall.'') * ''Ritardando'' – slowing down gradually; also see rallentando and ritenuto (abbreviations: ''rit.'', ''ritard.'') sometimes replaces allargando. * ''Ritenuto'' – slightly slower, but achieved more immediately than ''rallentando or'' ''ritardando''; a sudden decrease in tempo; temporarily holding back. (Note that the abbreviation for ''ritenuto'' can also be ''rit.'' Thus a more specific abbreviation is ''riten.'' Also, sometimes ''ritenuto'' does not reflect a tempo change but rather a 'character' change.) * ''

'' – free adjustment of tempo for expressive purposes, literally "stolen"—so more strictly, to take time from one beat to slow another * ''Slargando'' – gradually slowing down, literally "slowing down", "widening" or "stretching" * '' Stretto'' – in a faster tempo, often used near the conclusion of a section. (Note that in fugal compositions, the term ''stretto'' refers to the imitation of the subject in close succession, before the subject is completed, and as such, suitable for the close of the fugue. Used in this context, the term is not necessarily related to tempo.) * ''Stringendo'' – pressing on faster, literally "tightening" * ''Tardando'' – slowing down gradually (same as ''ritardando'') *''Tempo Primo'' – resume the original tempo While the base tempo indication (such as ''Allegro'') typically appears in large type above the staff, adjustments typically appear below the staff or, in the case of keyboard instruments, in the middle of the grand staff. They generally designate a ''gradual'' change in tempo; for immediate tempo shifts, composers normally just provide the designation for the new tempo. (Note, however, that when ''Più mosso'' or ''Meno mosso'' appears in large type above the staff, it functions as a new tempo, and thus implies an immediate change.) Several terms, e.g., ''assai'', ''molto'', ''poco'', ''subito'', control how large and how gradual a change should be (see common qualifiers). After a tempo change, a composer may return to a previous tempo in two ways: * ''a tempo'' – returns to the base tempo after an adjustment (e.g. ''ritardando ... a tempo'' undoes the effect of the ritardando). * ''Tempo primo'' or ''Tempo Io'' – denotes an immediate return to the piece's original base tempo after a section in a different tempo (e.g. ''Allegro ... Lento ... Moderato ... Tempo Io'' indicates a return to the ''Allegro''). This indication often functions as a structural marker in pieces in binary form. These terms also indicate an immediate, not a gradual, tempo change. Although they are Italian, composers tend to employ them even if they have written their initial tempo marking in another language.


Tempo–rhythm interaction

One difficulty in defining tempo is the dependence of its perception on rhythm, and, conversely, the dependence of rhythm perception on tempo. Furthermore, the tempo-rhythm interaction is context dependent, as explained by

's complexity theory, this means such a representation of the data that minimizes the amount of memory. The example considered suggests two alternative representations of the same rhythm: as it is, and as the rhythm-tempo interaction — a two-level representation in terms of a generative rhythmic pattern and a “tempo curve”. Table 1 displays these possibilities both with and without pitch, assuming that one duration requires one byte of information, one byte is needed for the pitch of one tone, and invoking the repeat algorithm with its parameters R012 takes four bytes. As shown in the bottom row of the table, the rhythm without pitch requires fewer bytes if it is “perceived” as it is, without repetitions and tempo leaps. On the contrary, its melodic version requires fewer bytes if the rhythm is “perceived” as being repeated at a double tempo. Thus, the loop of interdependence of rhythm and tempo is overcome due to the simplicity criterion, which "optimally" distributes the complexity of perception between rhythm and tempo. In the above example, the repetition is recognized because of additional repetition of the melodic contour, which results in a certain redundancy of the musical structure, making the recognition of the rhythmic pattern "robust" under tempo deviations. Generally speaking, the more redundant the "musical support" of a rhythmic pattern, the better its recognizability under augmentations and diminutions, that is, its distortions are perceived as tempo variations rather than rhythmic changes:


Modern classical music

20th-century classical music introduced a wide range of approaches to tempo, particularly thanks to the influence of

and later postmodernism. While many composers have retained traditional tempo markings, sometimes requiring greater precision than in any preceding period, others have begun to question basic assumptions of the classical tradition like the idea of a consistent, unified, repeatable tempo. Graphic scores show tempo and rhythm in a variety of ways. Polytemporal compositions deliberately utilise performers playing at marginally different speeds. John Cage's compositions approach tempo in diverse ways. For instance ''

Electronic music


Extreme tempo

More extreme tempos are achievable at the same underlying tempo with very fast drum patterns, often expressed as drum rolls. Such compositions often exhibit a much slower underlying tempo, but may increase the tempo by adding additional percussive beats.

Beatmatching

In popular music genres such as disco, house music and electronic dance music, beatmatching is a technique that DJs use that involves speeding up or slowing down a record (or CDJ player, a speed-adjustable CD player for DJ use) to match the tempo of a previous or subsequent track, so both can be seamlessly mixed. Having beatmatched two songs, the DJ can either seamlessly crossfade from one song to another, or play both tracks simultaneously, creating a layered effect. DJs often beatmatch the underlying tempos of recordings, rather than their strict bpm value suggested by the kick drum, particularly when dealing with high tempo tracks. A 240 bpm track, for example, matches the beat of a 120 bpm track without slowing down or speeding up, because both have an underlying tempo of 120 quarter notes per minute. Thus, some soul music (around 75–90 bpm) mixes well with a drum and bass beat (from 150 to 185 bpm). When speeding up or slowing down a record on a turntable, the pitch and tempo of a track are linked: spinning a disc 10% faster makes both pitch and tempo 10% higher. Software processing to change the pitch without changing the tempo is called
pitch-shifting Pitch shifting is a sound recording technique in which the original pitch of a sound is raised or lowered. Effects units that raise or lower pitch by a pre-designated musical interval ( transposition) are called pitch shifters. Pitch and tim ...
. The opposite operation, changing the tempo without changing the pitch, is called time-stretching.
