Abstract

A system and methods for acquiring cadence and selecting a song version based on the acquired cadence are disclosed. If the system detects a new cadence, then a new song version that corresponds to the new cadence can be played. The new song version playback can start in a corresponding position as the location of playback in a currently-playing song version. Each related song version shares one or more characteristics, such as melody, but is different in at least one characteristic, such as tempo.

Claims

1. A computer readable data storage device storing instructions that, when executed by at least one processing device, causes a media-playback device to:

identify a song for playback, the song having a melody;

acquire a cadence associated with a repetitive-motion activity;

select a song version of a plurality of pre-recorded song versions of the song based on the cadence of the repetitive motion activity,

each of the plurality of pre-recorded song versions of the song being an arrangement of the melody of the song;

each of the plurality of pre-recorded song versions of the song having a different tempo than others of the plurality of pre-recorded song versions;

each of the plurality of pre-recorded song versions of the song being divided into a plurality of chapters; and

each of the plurality of pre-recorded song versions of the song having a same number of chapters; and

play the selected song version.

2. The computer readable data storage device of claim 1, wherein the repetitive-motion activity of the user is running.

3. The computer readable data storage device of claim 1, wherein each of the plurality of pre-recorded song versions has a tempo of between about 140 beats per minute and about 190 beats per minute.

4. The computer readable data storage device of claim 1, wherein the selected song version has a tempo that corresponds to the cadence of the repetitive-motion activity.

5. The computer readable data storage device of claim 1, further including:

a first set of song versions based on a composition at about 140 beats per minute;

a second set of song versions based on a composition at about 160 beats per minute; and

a third set of song versions based on a composition at about 175 beats per minute.

6. The computer readable data storage device of claim 5, the first set of song versions having a first song version length;

the second set of song versions having a second song version length;

the third set of song versions having a third song version length;

wherein a difference between the first song version length and the second song version length is no greater than three minutes;

wherein a difference between the first song version length and the third song version length is no greater than three minutes; and

wherein a difference between the second song version length and the third song version length is no greater than three minutes.

7. The computer readable data storage device of claim 5, wherein the first set of song versions have a tempo of about 140 beats per minute, about 145 beats per minute, about 150 beats per minute, and about 155 beats per minute;

wherein the second set of song versions have a tempo of about 160 beats per minute, about 165 beats per minute, and about 170 beats per minute; and

wherein the third set of song versions have a tempo of about 175 beats per minute, about 180 beats per minute, about 185 beats per minute, and about 190 beats per minute.

8. A method for playback of media content, the method comprising:

identifying a song for playback, the song having a melody;

acquiring a cadence associated with a repetitive-motion activity of a user;

selecting a song version from a plurality of pre-recorded song versions of the song based on the cadence,

each of the plurality of pre-recorded song versions being an arrangement of the melody of the song;

each of the plurality of pre-recorded song versions having a different tempo than each of the other plurality of pre-recorded song versions;

each of the plurality of pre-recorded song versions being divided into more than one chapter; and

each of the plurality of pre-recorded song versions having a same number of chapters; and

initiating playback of the song version.

9. The method for playback of media content of claim 8, further comprising monitoring for a change in cadence.

10. The method for playback of media content of claim 9, further comprising, upon detecting a new cadence, selecting a new song version based on the new cadence.

11. The method for playback of media content of claim 9, further comprising:

upon detecting a new cadence, determining a difference between the cadence and the new cadence; and

if the difference exceeds a predetermined threshold, selecting a new song version based on the new cadence.

12. The method for playback of media content of claim 9, further comprising:

upon detecting a new cadence, determining a difference between the cadence and the new cadence; and

monitoring the new cadence for a predetermined duration;

if the difference exceeds a predetermined threshold for the predetermined duration, selecting a new song version based on the new cadence.

13. The method of playback of media content of claim 8, wherein each of the plurality of pre-recorded song versions has a tempo of between about 140 beats per minute and about 190 beats per minute.

14. The method of playback of media content of claim 8, wherein selecting a song version includes selecting from a first set of song versions, a second set of song versions, and a third set of song versions.

15. The method of playback of media content of claim 14, wherein the first set of song versions are based on a composition at about 140 beats per minute;

wherein the second set of song versions are based on a composition at about 160 beats per minute; and

wherein the third set of song versions are based on a composition at about 175 beats per minute.

16. A media server comprising:

a media data store encoded on at least one computer readable data storage device, the media data store comprising;

a plurality of pre-recorded song versions of a song, the song having a melody,

each of the plurality of pre-recorded song versions being an arrangement of the melody of the song,

each of the plurality of pre-recorded song versions being divided into more than one chapter,

each of the plurality of pre-recorded song versions having a same number of chapters; and

each of the plurality of pre-recorded song versions being different from each of the other plurality of pre-recorded song versions in tempo; and

a computing device in data communication with the media data store, wherein the computing device is programmed to transmit at least one of the song versions to a media-playback device based on a cadence of a repetitive-motion activity.

17. The media server of claim 16, wherein each of the song versions has a track length of between about 20 minutes and about 60 minutes.

18. The media server of claim 16, wherein each of the song versions is divided into one or more chapters, each chapter having a length of between about 2 minutes and about 10 minutes.

19. The media server of claim 17, wherein the song versions include a set of first song versions, a set of second song versions, and a set of third song versions.

20. The media server of claim 19, wherein the first set of song versions include recordings at about 140 beats per minute, about 145 beats per minute, about 150 beats per minute, and 155 beats per minute;
