Musical improvisation
Spontaneous musical composition performed in the moment.
Musical improvisation, also known as musical extemporization, is the creative activity of immediate musical composition that combines performance with communication of emotions and instrumental technique as well as spontaneous response to other musicians. It has been a valued skill throughout the Western art music tradition from the Medieval period through the Romantic period, and remains a major part of some types of 20th-century music such as blues, rock music, jazz, and jazz fusion.

Lore & Background
Throughout the eras of the Western art music tradition, including the Medieval, Renaissance, Baroque, Classical, and Romantic periods, improvisation was a valued skill. J. S. Bach, Handel, Mozart, Beethoven, Chopin, Liszt, and many other famous composers and musicians were known especially for their improvisational skills. The earliest treatises on polyphony, such as the Musica enchiriadis from the ninth century, indicate that added parts were improvised for centuries before the first notated examples, though it was only in the fifteenth century that theorists began making a hard distinction between improvised and written music.
Reader's Guide
Musical improvisation has played a central role in the development of Western art music, from the improvised organum of the Medieval period to the elaborate ornamentation and basso continuo realization of the Baroque era. In the Classical and Romantic periods, composers such as Mozart and Beethoven left written examples of their improvisations in the form of variations, sonatas, and cadenzas. However, in the 20th and early 21st century, as common practice Western art music performance became institutionalized in symphony orchestras, opera houses and ballets, improvisation has played a smaller role. At the same time, some contemporary composers from the 20th and 21st century have increasingly included improvisation in their creative work. In Indian classical music, improvisation remains a core component and an essential criterion of performances, with raga serving as the tonal framework for composition and improvisation.
