Patent for Sale:

Play-along prompted in time with a musical performance.    

System and technique for the creation and playback of animated, interpretive, musical notation and audio synchronized with the recorded performance of an original artist.


A music application guides a user with some musical experience through the steps of creating and editing a musical enhancement file that enhances and plays in synchronicity with an audio signal of an original artist's recorded performance. This enables others, perhaps with lesser musical ability than the original artist, to play-along with the original artist by following melodic, chordal, rhythmic, and verbal prompts. The music application accounts for differences in the timing of the performance from a standard tempo by guiding the user through the process of creating a tempo map for the performance and by associating the tempo map with MIDI information of the enhancement file. Enhancements may contain MIDI information, audio signal information, and/or video signal information which may be played back in synchronicity with the recorded performance to provide an aural and visual aid to others playing-along who may have less musical experience.

Primary Application of the Technology

Games - play along or sing along games which score participants for accuracy.
Musical education and training.
Musical enjoyment, such as karaoke on a cell phone for voice and other instruments.

The Problem Solved by the Technology

The technology greatly reduces the difficulty in learning to play an instrument. Prompting removes the need for the grueling repetitive practice most musicians go through to learn and memorise a song, and prompting at beginner levels enables non-musicians to learn by accompanying their favourite songs immediately. All gain instant gratification by playing along with their favourite songs and so more rapidly build skills to play independently as well.

How the Technology Solves the Problem

The technology uses audio or visual prompts played to the user in time with a recorded performance so the movements, chords, rhythm or melody are shown when the user needs to respond. The creation of such musical enhancements in synch with the performance is covered as well.

Competitive Advantage

Can be applied to any existing recording and enables anyone to contribute synchronised musical enhancements to a song and anyone to play them. Studio master recording or new special purpose recordings are not needed.

The seller would like to be granted a license back.

The seller may consider selling these patents individually.

Additional Information

Some examples of play-along in action are available for review. This introduces another innovation using an open tuning for guitar which simplifies playing popular music and uses chord prompts corresponding to fret numbers embedded in the lyrics. For some songs the lyrics with the chord prompts embedded are shown as sub-titles on videos displayed in time with the performance and demonstrate the play-along invention.
