Workers Union (1975) is a composition by Louis Andriessen intended for any loud-sounding group of instruments; Andriessen did not want to handicap orchestras by providing a list of instruments. [1]
It is a melodically indeterminate piece; this means there is no key and no defined melody. [2] The piece is very strict rhythmically, with only a guide to lower or raise pitches. Sections may be repeated as many times as the conductor wishes, resulting in varying performance lengths. Every instrument plays different notes that follow the same rhythm and ascending or descending patterns. This creates an atonal piece with many polyphonic phrases. There are points in the piece where the ensemble splits into two groups. The groups alternate lines before coming back together again. If executed properly, the piece sounds mechanical as the instrumentation operates in perfect unison.
Before simply playing the rhythms indicated on the score, one must select a middle pitch. There is a single line through the center of the staff that indicates the aforementioned middle pitch - a pitch line. Each musician chooses their own pitch that will represent the midway point. Notes that are written above the line should be played higher than the preselected pitch and vice versa.
It is important for the musician to remember their middle pitch. During long lines or complex rhythms, one must make sure there is adequate room between what they're playing and the pitch line.
Music is the art of arranging sounds in time to produce a composition through the elements of melody, harmony, rhythm, and timbre. It is one of the cultural universal aspects of all human societies. General definitions of music include common elements such as pitch, rhythm, dynamics, and the sonic qualities of timbre and texture. Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική . See glossary of musical terminology.
Music notation or musical notation is any system used to visually represent aurally perceived music played with instruments or sung by the human voice through the use of written, printed, or otherwise-produced symbols, including notation for durations of absence of sound such as rests.
The trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet with the highest register in the brass family, to the bass trumpet, which is pitched one octave below the standard B♭ or C Trumpet.
A clef is a musical symbol used to indicate which notes are represented by the lines and spaces on a musical stave. When a clef is placed on a stave it assigns a particular note to one of the five lines. This line becomes a reference point by which the names of the other notes on the stave are determined.
In Western musical notation, the staff (US) or stave (UK) is a set of five horizontal lines and four spaces that each represent a different musical pitch or in the case of a percussion staff, different percussion instruments. Appropriate music symbols, depending on the intended effect, are placed on the staff according to their corresponding pitch or function. Musical notes are placed by pitch, percussion notes are placed by instrument, and rests and other symbols are placed by convention.
String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner.
Music theory is the study of the practices and possibilities of music. The Oxford Companion to Music describes three interrelated uses of the term "music theory". The first is the "rudiments", that are needed to understand music notation ; the second is learning scholars' views on music from antiquity to the present; the third a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built."
A transposing instrument is a musical instrument for which music notation is not written at concert pitch. For example, playing a written middle C on a transposing instrument produces a pitch other than middle C — that sounding pitch identifies the interval of transposition when describing the instrument. Playing a written C on clarinet or soprano saxophone produces a concert B♭, so these are referred to as B♭ instruments. Providing transposed music for these instruments is a convention of musical notation. The instruments do not transpose the music, rather their music is written at a transposed pitch.
Sheet music is a handwritten or printed form of musical notation that uses musical symbols to indicate the pitches, rhythms, or chords of a song or instrumental musical piece. Like its analogs – printed books or pamphlets in English, Arabic, or other languages – the medium of sheet music typically is paper, although the access to musical notation since the 1980s has included the presentation of musical notation on computer screens and the development of scorewriter computer programs that can notate a song or piece electronically, and, in some cases, "play back" the notated music using a synthesizer or virtual instruments.
The triangle is an idiophone type of musical instrument in the percussion family. It is a bar of metal, usually steel but sometimes other metals such as beryllium copper, bent into a triangle shape. The instrument is usually held by a loop of some form of thread or wire at the top curve. While the triangle theoretically has a definite pitch, it is obscured by the overtones that are produced when struck.
In music, the dynamics of a piece is the variation in loudness between notes or phrases. Dynamics are indicated by specific musical notation, often in some detail. However, dynamics markings still require interpretation by the performer depending on the musical context: for instance a piano (quiet) marking in one part of a piece might have quite different objective loudness in another piece, or even a different section of the same piece. The execution of dynamics also extends beyond loudness to include changes in timbre and sometimes tempo rubato.
This is a list of musical terms that are likely to be encountered in printed scores, music reviews, and program notes. Most of the terms are Italian, in accordance with the Italian origins of many European musical conventions. Sometimes, the special musical meanings of these phrases differ from the original or current Italian meanings. Most of the other terms are taken from French and German, indicated by "Fr." and "Ger.", respectively.
In music, unison is two or more musical parts that sound either the same pitch or pitches separated by intervals of one or more octaves, usually at the same time. Rhythmic unison is another term for homorhythm.
A bassline is the term used in many styles of music, such as jazz, blues, funk, dub and electronic, traditional music, or classical music for the low-pitched instrumental part or line played by a rhythm section instrument such as the electric bass, double bass, cello, tuba or keyboard.
In musical notation, a bar is a segment of time corresponding to a specific number of beats in which each beat is represented by a particular note value and the boundaries of the bar are indicated by vertical bar lines. Dividing music into bars provides regular reference points to pinpoint locations within a musical composition. It also makes written music easier to follow, since each bar of staff symbols can be read and played as a batch.
Ear training or aural skills is a music theory study in which musicians learn to identify pitches, intervals, melody, chords, rhythms, solfeges, and other basic elements of music, solely by hearing. The application of this skill is analogous to taking dictation in written/spoken language. As a process, ear training is in essence the inverse of sight-reading, the latter being analogous to reading a written text aloud without prior opportunity to review the material. Ear training is typically a component of formal musical training and is a fundamental, essential skill required in music schools.
The guqin is a plucked seven-string Chinese musical instrument. It has been played since ancient times, and has traditionally been favoured by scholars and literati as an instrument of great subtlety and refinement, as highlighted by the quote "a gentleman does not part with his qin or se without good reason," as well as being associated with the ancient Chinese philosopher Confucius. It is sometimes referred to by the Chinese as "the father of Chinese music" or "the instrument of the sages". The guqin is not to be confused with the guzheng, another Chinese long stringed instrument also without frets, but with moveable bridges under each string.
A neume is the basic element of Western and Eastern systems of musical notation prior to the invention of five-line staff notation.
In music, the range, or chromatic range, of a musical instrument is the distance from the lowest to the highest pitch it can play. For a singing voice, the equivalent is vocal range. The range of a musical part is the distance between its lowest and highest note.
In music, transcription is the practice of notating a piece or a sound which was previously unnotated and/or unpopular as a written music, for example, a jazz improvisation or a video game soundtrack. When a musician is tasked with creating sheet music from a recording and they write down the notes that make up the piece in music notation, it is said that they created a musical transcription of that recording. Transcription may also mean rewriting a piece of music, either solo or ensemble, for another instrument or other instruments than which it was originally intended. The Beethoven Symphonies transcribed for solo piano by Franz Liszt are an example. Transcription in this sense is sometimes called arrangement, although strictly speaking transcriptions are faithful adaptations, whereas arrangements change significant aspects of the original piece.
