Musical composition: Musical composition can refer to an original piece of music, either a song or an instrumental music piece, the structure of a musical piece, or the process of creating or writing a new song or piece of music.  People who create new compositions are called composers in classical music.  In popular music and traditional music, the creators of new songs are usually called songwriters; with songs, the person who writes new words for a song is the lyricist.  "Composition" is the act or practice of creating a song or other piece of music.  In many cultures, including Western classical music, the act of composing typically includes the creation of music notation, such as a sheet music "score", which is then performed by the composer or by other instrumental musicians or singers.  In popular music and traditional music, songwriting may involve the creation of a basic outline of the song, called the lead sheet, which sets out the melody, lyrics and chord progression.  In classical music, orchestration (choosing the instruments of a large music ensemble such as an orchestra which will play the different parts of music, such as the melody, accompaniment, countermelody, bassline and so on) is typically done by the composer, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration.  In some cases, a pop or traditional songwriter may not use written notation at all, and instead compose the song in her mind and then play, sing and/or record it from memory.  In jazz and popular music, notable sound recordings by influential performers are given the weight that written or printed scores play in classical music.

Meditation music: Meditation music is music performed to aid in the practice of meditation.  It can have a specific religious content, but also more recently has been associated with modern composers who use meditation techniques in their process of composition, or who compose such music with no particular religious group as a focus.  The concept also includes music performed as an act of meditation.

Conductorless orchestra: The conductorless orchestra, sometimes referred to as a self-conducted orchestra or unconducted orchestra, is an instrumental ensemble that functions as an orchestra but is not led or directed by a conductor.  Most conductorless orchestras are smaller in size, and generally perform chamber orchestra repertoire.  Several conductorless orchestras are made up of only strings and focus primarily on string orchestra repertoire.  Conductorless orchestras generally come from the classical music tradition and perform standard repertoire, but many conductorless orchestras promote or specialise in contemporary classical music repertoire.  Many contemporary classical music ensembles also regularly perform without a conductor.
