People make new music. We call this musical composition. 
Composers use many ways to make music. In classical music, they often write a score. A score is a set of written notes on paper. This helps musicians play the music together. In pop music, a songwriter might use a lead sheet. This is a simple guide with the melody and chords.
Making music can involve many tools. Some use a large orchestra with strings and brass. Others use electric guitars or digital keyboards. Some even use computers to pick sounds. A composer must choose the right tools for the job. They must make sure the sounds fit well together. This is a wonderful way to share new ideas with the world.
Musical composition is the act of creating new music. 
There are many ways to build a piece of music. In classical music, a composer often writes a score. A score is a set of written notes on paper. This helps large groups like orchestras play together correctly. In popular music, a songwriter might use a lead sheet.
History shows us that music has changed with new tools. During the Baroque era from 1600 to 1750, music used only acoustic instruments. These included strings, brass, woodwinds, and the pipe organ. After 1960, popular music began using many electric instruments. Today, a pop band might use an electric guitar and a digital synthesizer. Even in the 20th century, composers like John Cage used chance to make music. This is called aleatoric music, which relies on random sounds.
Composers must make many important choices about sound. They decide on the melody, rhythm, and the instruments to use. This task of choosing instruments is called orchestration. A composer might write for a full orchestra or a small chamber group. They might even write a solo for just one person. Elizabeth Swados noted that instruments must complement each other. For example, a loud tuba might drown out a tiny piccolo. 
Technology has opened even more doors for making music. In the 20th and 21st centuries, people started using computer programs to compose. Some artists even use EEG headsets to turn brainwaves into music. This was used in a project called Mindtunes with the artist DJ Fresh. Composition is a broad field that includes many different styles. It covers everything from Western classical music to African percussion. It even includes the spontaneous sounds of free jazz performers.
Musical composition is the creative process of designing an original work of music. 
There are several distinct methods used to document or prepare a composition for performance. In Western classical traditions, composers often create a score. A score is a written musical notation that provides detailed instructions for every player. In popular or jazz music, a songwriter might instead create a lead sheet.
Composition involves complex technical decisions regarding instrumentation and arrangement. Orchestration is the process of choosing which instruments will play specific parts. A composer must decide on the melody, the accompaniment, the countermelody, and the bassline. This might involve a full orchestra with strings, woodwinds, brass, and percussion. It could also involve a concert band or a small chamber group. Sometimes, a composer writes a solo, which is music for just one instrument. Elizabeth Swados noted that composers must ensure instruments complement rather than compete with one another. For instance, a loud tuba could easily drown out a small piccolo.
Musical styles have evolved significantly alongside changes in technology. During the Baroque era, which lasted from 1600 to 1750, composers used only acoustic and mechanical instruments. These included the harpsichord, pipe organ, strings, and woodwinds. Following 1960, popular music began to rely heavily on electric and electronic instruments. A modern pop band might use an electric guitar with electronic effects, digital synthesizers, and electronic drums. In the 20th and 21st centuries, technology has introduced even more radical methods. Composers now use computer programs to select sounds or generate musical structures. Some artists have even used EEG headsets to translate brainwaves into musical compositions.
History shows that composition can also embrace randomness and chance. This is known as aleatoric music, a style associated with 20th-century composers like John Cage, Morton Feldman, and Witold Lutosławski. While a classical piece is often precisely notated, aleatoric music allows for indeterminate elements. A common example of this chance-based sound is the way wind chimes jingle in a breeze. Other modern techniques include musique concrète, where composers use non-musical sounds like sirens or typewriters. Even the study of composition has expanded beyond Western classical music to include spontaneous improvisation. This includes the work of free jazz performers and African percussionists like Ewe drummers.
When a composition is ready to be played, it undergoes a process called interpretation. Even with precise notation, performers must make individual choices. They decide on the tempo, which is the speed of the music, and the phrasing of melodies. These choices are part of a performer's unique style. The standard set of choices used in a specific time and place is called performance practice. Once a work is created, it is also protected by copyright laws. This government-granted monopoly gives the owner exclusive rights to publish the music. This ensures that composers or their employers can control how their work is used and shared.
Composition is a broad field that manipulates several key musical elements. According to Jean-Benjamin de La Roque, it involves the manipulation of harmony, melody, form, rhythm, and timbre. The form of a piece can be through-composed, meaning every section is different. Other forms include strophic, rondo, or verse-chorus structures. Some music is built around specific scales or modes, such as the maqam in Middle Eastern music. Whether through rigid notation or spontaneous improvisation, composition remains a diverse and evolving human endeavor.
