Thus, the shape and energy of the piece, if not the duration, is always the same: a tendency towards sparser texture and eventually silence as the metronomes unwind. The piece, notated as a short text score, lasts as long as it takes one hundred mechanical metronomes, all set in motion at the same time, to unwind and stop ticking. But no piece in Ligeti’s catalogue better distills the composer’s fascination with chaos, order, and broken systems. To sum up, here are some common examples.Gÿorgy Ligeti’s 1962 composition for 100 metronomes, Poème Symphonique, owes much of its success to its presentation as a ridiculous spectacle. The number of beats per measure can instead be determined by dividing the upper number by three. So, if the lower number is 8 the beat unit must be the dotted quarter note, since it is three times an eighth note. To identify which type of note represents one beat, you have to multiply the note value represented by the lower number by three. Unlike simple time, compound time uses a dotted note for the beat unit.

The most common lower number in a compound time signature is 8. Compound time signatures are distinguished by an upper number which is commonly 6, 9 or 12.

In compound time signatures, each beat is divided into three equal parts.The most common simple time signatures are 2/4, 3/4, 4/4 (often indicated with a “C” simbol) and 2/2 (often indicated with a “cut C” simbol). In simple time signatures, each beat is divided into two equal parts.Time signatures actually come in two flavors: simple and compound. You should beware, however, that this interpretation is only correct when handling simple time signatures. the lower number indicates the note value which represents one beat: “2” stands for the half note, “4” for the quarter note, “8” for the eighth note and so on.the upper number indicates how many beats there are in a measure.Time signatures are found at the beginning of a musical piece, after the clef and the key signature. On the other hand, if the fastest notes of a work are impossible to play well, the tempo is probably too fast.Ī true understanding of time signatures is crucial towards a correct use of the metronome. If a musical passage does not make sense, the tempo might be too slow. The tempo of a piece will depend on the actual rhythms in the music itself, as well as the performer and the style of the music. Traditionally, metronomes display some of the most common Italian tempo markings (“Adagio”, “Allegro”, etc.) alongside the BPM slider, but the correspondence of words to numbers can by no means be regarded as precise for every piece. You can search for these foreign terms in our music glossary. Most of these words are Italian, a result of the fact that many of the most important composers of the 17th century were Italian, and this period was when tempo indications were used extensively for the first time. Whether a music piece has a mathematical time indication or not, in classical music it is customary to describe the tempo of a piece by one or more words, which also convey moods. The tempo is typically written at the start of a piece of music, and in modern music it is usually indicated in beats per minute (BPM). In musical terminology, tempo (Italian for “time”) is the speed or pace of a given piece.
