Music is generally defined as the art of arranging sound to create some combination of form, harmony, melody, rhythm, or otherwise expressive content. Definitions of music vary depending on culture, though it is an aspect of all human societies and a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, psychology, and therapeutic contexts. Music may be performed or improvised using a vast range of instruments, including the human voice.
Orchestration is the study or practice of writing music for an orchestra or of adapting music composed for another medium for an orchestra. Also called "instrumentation", orchestration is the assignment of different instruments to play the different parts of a musical work. For example, a work for solo piano could be adapted and orchestrated so that an orchestra could perform the piece, or a concert band piece could be orchestrated for a symphony orchestra.
In Western musical notation, the staff (US) or stave (UK) also occasionally referred to as a pentagram 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.
In music, ornaments or embellishments are musical flourishes—typically, added notes—that are not essential to carry the overall line of the melody, but serve instead to decorate or "ornament" that line, provide added interest and variety, and give the performer the opportunity to add expressiveness to a song or piece. Many ornaments are performed as "fast notes" around a central, main note.
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. However, 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.
A grace note is a kind of music notation denoting several kinds of musical ornaments. It is usually printed smaller to indicate that it is melodically and harmonically nonessential. When occurring by itself, a single grace note indicates either an acciaccatura when notated with an oblique stroke through the stem, or an appoggiatura when notated without. When they occur in groups, grace notes can be interpreted to indicate any of several different classes of ornamentation, depending on interpretation. For percussion, such as drums, a related concept are ghost notes — supportive snare-hits at a lower volume.
Conducting is the art of directing a musical performance, such as an orchestral or choral concert. It has been defined as "the art of directing the simultaneous performance of several players or singers by the use of gesture." The primary duties of the conductor are to interpret the score in a way that reflects the specific indications in that score, set the tempo, ensure correct entries by ensemble members, and "shape" the phrasing where appropriate. Conductors communicate with their musicians primarily through hand gestures, usually with the aid of a baton, and may use other gestures or signals such as facial expression and eye contact. A conductor usually supplements their direction with verbal instructions to their musicians in rehearsal.
In music, the dynamics of a piece are the variation in loudness between notes or phrases. Dynamics are indicated by specific musical notation, often in some detail. However, dynamics markings require interpretation by the performer depending on the musical context: a specific marking may correspond to a different volume between pieces or even sections of one piece. The execution of dynamics also extends beyond loudness to include changes in timbre and sometimes tempo rubato.
A variety of musical terms are 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.
The bass clarinet is a musical instrument of the clarinet family. Like the more common soprano B♭ clarinet, it is usually pitched in B♭, but it plays notes an octave below the soprano B♭ clarinet. Bass clarinets in other keys, notably C and A, also exist, but are very rare. Bass clarinets regularly perform in orchestras, wind ensembles and concert bands, and occasionally in marching bands, and play an occasional solo role in contemporary music and jazz in particular.
A rest is the absence of a sound for a defined period of time in music, or one of the musical notation signs used to indicate that.
The numbered musical notation is a cipher notation system used in Mainland China, Taiwan, Hong Kong, and to some extent in Japan, Indonesia, Malaysia, Australia, Ireland, the United Kingdom, the United States and English-speaking Canada. It dates back to the system designed by Pierre Galin, known as Galin-Paris-Chevé system. It is also known as Ziffernsystem, meaning "number system" or "cipher system" in German.
Mensural notation is the musical notation system used for polyphonic European vocal music from the late 13th century until the early 17th century. The term "mensural" refers to the ability of this system to describe precisely measured rhythmic durations in terms of numerical proportions between note values. Its modern name is inspired by the terminology of medieval theorists, who used terms like musica mensurata or cantus mensurabilis to refer to the rhythmically defined polyphonic music of their age, as opposed to musica plana or musica choralis, i.e., Gregorian plainchant. Mensural notation was employed principally for compositions in the tradition of vocal polyphony, whereas plainchant retained its own, older system of neume notation throughout the period. Besides these, some purely instrumental music could be written in various forms of instrument-specific tablature notation.
A lead sheet or fake sheet is a form of musical notation that specifies the essential elements of a popular song: the melody, lyrics and harmony. The melody is written in modern Western music notation, the lyric is written as text below the staff and the harmony is specified with chord symbols above the staff.
Articulation is a musical parameter that determines how a single note or other discrete event is sounded. Articulations primarily structure an event's start and end, determining the length of its sound and the shape of its attack and decay. They can also modify an event's timbre, dynamics, and pitch. Musical articulation is analogous to the articulation of speech, and during the Baroque and Classical periods it was taught by comparison to oratory.
In music, fingering, or on stringed instruments sometimes also called stopping, is the choice of which fingers and hand positions to use when playing certain musical instruments. Fingering typically changes throughout a piece; the challenge of choosing good fingering for a piece is to make the hand movements as comfortable as possible without changing hand position too often. A fingering can be the result of the working process of the composer, who puts it into the manuscript, an editor, who adds it into the printed score, or the performer, who puts his or her own fingering in the score or in performance.
Fingering...also stopping...(1) A system of symbols for the fingers of the hand used to associate specific notes with specific fingers....(2)Control of finger movements and position to achieve physiological efficiency, acoustical accuracy [frequency and amplitude] and musical articulation.
Percussion notation is a type of musical notation indicating notes to be played by percussion instruments. As with other forms of musical notation, sounds are represented by symbols which are usually written onto a musical staff.
The string section is composed of bowed instruments belonging to the violin family. It normally consists of first and second violins, violas, cellos, and double basses. It is the most numerous group in the standard orchestra. In discussions of the instrumentation of a musical work, the phrase "the strings" or "and strings" is used to indicate a string section as just defined. An orchestra consisting solely of a string section is called a string orchestra. Smaller string sections are sometimes used in jazz, pop, and rock music and in the pit orchestras of musical theatre.
In traditional Arabic music, maqam is the system of melodic modes, which is mainly melodic. The word maqam in Arabic means place, location or position. The Arabic maqam is a melody type. It is "a technique of improvisation" that defines the pitches, patterns, and development of a piece of music and is "unique to Arabian art music". There are 72 heptatonic tone rows or scales of maqamat. These are constructed from augmented, major, neutral, and minor seconds. Each maqam is built on a scale, and carries a tradition that defines its habitual phrases, important notes, melodic development and modulation. Both compositions and improvisations in traditional Arabic music are based on the maqam system. Maqamat can be realized with either vocal or instrumental music, and do not include a rhythmic component.
Abbreviations in music are of two kinds, namely, abbreviations of terms related to musical expression, and the true musical abbreviations by the help of which certain passages, chords, etc., may be notated in a shortened form, to the greater convenience of both composer and performer. Abbreviations of the first kind are like most abbreviations in language; they consist for the most part of the initial letter or first syllable of the word employed—as for instance, p or f for the dynamic markings piano and forte, cresc. for crescendo, Ob. for oboe, Fag. for bassoon. This article is about abbreviations used in music notation.
