A method relating to synchronize MIDI file with video includes acquiring a video and a MIDI file, and identifying timing of a video frame. The method also includes converting timing into tick information and editing a tick of the MIDI file. The method further includes detecting the MIDI file corresponding to the video frame, and playing a musical instrument based on the MIDI file corresponding to the video.

A hand-held strumming device includes a hollow body, a power source, a motor, a regulator, and a strummer. The power source is disposed in the hollow body. The motor is in electrical communication with the power source. The regulator is in electrical communication with both the motor and the power source. The regulator is configured to selectively adjust a rotational speed of the motor. The strummer is rotatably disposed on the disk. The strummer is configured to be presented to strings of a stringed instrument upon rotation of the motor to strum the strings.

The stringed instrument-playing machine is an electromechanical device. The stringed instrument-playing machine is a musical instrument. The stringed instrument-playing machine is an automated structure. The stringed instrument-playing machine automatically announces the musical notes of a song. The stringed instrument-playing machine comprises a stringed instrument and a playing device. The stringed instrument-playing machine incorporates a stringed instrument and a playing device. The stringed instrument is a mechanical structure that generates audible sounds in the form of a plurality of notes. The playing device is an electromechanical device. The playing device is an electrically powered device. The playing device mechanically plays the stringed instrument. By playing the stringed instrument is meant that the playing device determines and causes the stringed instrument to generate: a) the notes that are played; b) the order that the notes are played; and, c) the length of time each note is played.
