The history of film technology traces the development of film technology from the initial development of "moving pictures" at the end of 19th century to the present time.
 Motion pictures were initially exhibited as a fairground novelty and developed into one of the most important tools of communication and entertainment in the 20th century.
 Major developments in motion picture technology have included the adoption of synchronized motion picture sound, color motion picture film, and the adoption of digital film technologies to replace physical film stock at both ends of the production chain by digital image sensors and projectors.

In country music, walkdown is a bassline which connects two root position chords whose roots are a third apart, often featuring an inverted chord to go between the root notes of the first two chords.
 See: slash chord.
 A walkup would be the converse.
 For example the chords G Major and E minor (a minor third apart) may be joined by an intervening chord to create stepwise motion in the bass: G-D/F♯ -Em (I-V6/4-vi).
 The second chord, D Major, is performed with its third note, the F#, in the bass.
 Walkdowns may be performed by the upright bass player, the electric bass player, the guitarist, or a piano player.
Bass Player is a magazine for bassists. Each issue offers a variety of artist interviews, lessons, equipment reviews, and a complete transcribed bass line from a popular song.
