MPEG-1 and/or MPEG-2 Audio Layer III, more commonly referred to as MP3 (or mp3), is an audio coding format for digital audio which uses a form of lossy data compression, which are data encoding methods that use inexact approximations and partial data discarding to reduce file sizes significantly, typically by a factor of 10, in comparison with a CD, yet still sound like the original uncompressed audio to most listeners.

Compared to CD quality digital audio, MP3 compression commonly achieves 75 to 95% reduction in size.

MP3 files are thus 1/4 to 1/20 the size of the original digital audio stream.

This is important for both transmission and storage concerns.

The basis for such comparison is the CD digital audio format which requires 1411200 bit/s.

A commonly used MP3 encoding setting is CBR 128 kbit/s resulting in file size 1/11 (=9% or 91% compression) of the original CD-quality file.

Sheet music is a handwritten or printed form of music notation that uses modern musical symbols to indicate the pitches (melodies), rhythms and/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 (or, in earlier centuries, papyrus or parchment), 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.

In music transposition refers to the process, or operation, of moving a collection of notes (pitches or pitch classes) up or down in pitch by a constant interval.

A musical instrument is an instrument created or adapted to make musical sounds.

In principle, any object that produces sound can be a musical instrument—it is through purpose that the object becomes a musical instrument.

The history of musical instruments dates to the beginnings of human culture.

Early musical instruments may have been used for ritual, such as a trumpet to signal success on the hunt, or a drum in a religious ceremony.

Cultures eventually developed composition and performance of melodies for entertainment.

Musical instruments evolved in step with changing applications.

Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music.

While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods.

The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period.

The major time divisions of Western art music are as follows:
