Abstract

One embodiment of a musical sonification system and method receives a data stream including different data parameters. The sonification system may apply different sonification processes to the different data parameters to produce a musical rendering of the data stream. In one embodiment, the sonification system and method maps data parameters related to options trades to pitch values corresponding to musical notes in an equal tempered scale.

receiving said data stream including different data parameters;

obtaining data values for at least two of said different data parameters in said data stream;

determining pitch values corresponding to said data values obtained for said at least two of said different data parameters, wherein said pitch values correspond to musical notes; and

playing said musical notes for said at least two of said different data parameters to produce a musical rendering of said data stream, wherein changes in said musical notes indicate changes of said data parameters in said data stream.

2. The method of claim 1 wherein said pitch values correspond to notes in an equal tempered scale.

3. The method of claim 1 wherein determining pitch values comprises determining at least first and second parameter pitch values corresponding to data values obtained for at least first and second data parameters, wherein said first and second parameter pitch values determined for said first and second data parameters are within first and second different pitch ranges, respectively.

4. The method of claim 3 wherein playing said musical notes comprises playing musical notes using different instruments for said first and second data parameters.

5. The method of claim 3 wherein playing said musical notes comprises:

playing at least one sustained first parameter note at said first parameter pitch value in said first pitch range; and

playing at least one reference note at an initial pitch value in said second pitch range followed by at least one second parameter note at said second parameter pitch value in said second pitch range.

6. The method of claim 5 wherein determining pitch values comprises determining at least one third parameter pitch value corresponding to a data value obtained for at least a third data parameter, wherein said third parameter pitch value corresponds to a musical note spaced from said second parameter note by an interval, and wherein playing said musical notes comprises playing at least one third parameter note following said second parameter note.

7. The method of claim 6 wherein a number of said third parameter notes to be played corresponds to a magnitude of said data value for said third data parameter.

8. The method of claim 7 wherein a plurality of third parameter notes are played together as a harmony.

9. The method of claim 8 wherein said harmony includes at least one of a major triad and a minor triad.

10. The method of claim 6 wherein a plurality of third parameter notes are played alternatively in sequence with said second parameter note, wherein a tempo of said notes played in sequence corresponds to a magnitude of said data value for said third data parameter.

11. The method of claim 1 wherein said data stream includes a series of data elements corresponding to events being monitored, each of said data elements including raw data for said data parameters related to a respective event.

12. The method of claim 11 wherein obtaining data values for at least one of said data parameters includes calculating a moving sum of said raw data over a period of time as said data elements are received.

13. The method of claim 11 wherein said data stream is a financial data stream, and wherein said data elements correspond to financial trading events.

14. The method of claim 13 wherein said financial data stream includes financial trading events for a portfolio, and wherein said musical rendering indicates portfolio changes of said data parameters.

15. The method of claim 11 wherein said data stream includes data elements corresponding to options trades, and wherein said data parameters include at least one of a delta, gamma and vega resulting from an option trade, and wherein each of said data elements further includes values representative of an expiration and strike related to said option trade.

16. The method of claim 1 wherein musical notes for at least two of said data parameters are played together as a harmony, said harmony including at least one of a major triad and a minor triad.

17. A method of musical sonification of a data stream for monitoring option trading, said method comprising:

receiving a data stream including a series of data elements corresponding to options trades being monitored, each of said data elements including data parameters related to a respective trade;

mapping said data parameters to pitch as said data stream is received, wherein at least two of said data parameters are mapped to pitch values within a different pitch range, wherein said pitch values correspond to musical notes; and

playing said musical notes corresponding to said pitch values to produce a musical rendering of said data stream, wherein changes in said musical notes indicate changes in said data parameters.

18. The method of claim 17 wherein said data parameters include at least a delta, gamma and vega, wherein mapping changes comprises calculating moving sums of each of said delta, gamma and vega over a period of time, and wherein said pitch values are determined based on said moving sums.

19. The method of claim 18 wherein playing said musical notes comprises playing sustained musical notes for said delta.

20. The method of claim 18 wherein playing said musical notes comprises playing reference notes followed by musical notes for said gamma and said vega.

21. The method of claim 17 wherein each of said data elements includes a value representative of an expiration related to said trade, wherein said expiration is mapped to additional pitch values corresponding to musical notes, wherein playing said musical notes comprises playing said musical notes corresponding to said additional pitch values for said expiration in sequence with a musical note played for at least one of said data parameters, and wherein a tempo of said sequence indicates a magnitude of said value for said expiration.

22. The method of claim 17 wherein each of said data elements includes values representative of a strike related to said trade, wherein said strike is mapped to additional pitch values corresponding to musical notes, wherein playing said musical notes comprises playing said musical notes corresponding to said additional pitch values for said strike together with a musical note played for at least one of said data parameters to form a harmony, and wherein a number of said notes played together indicates a magnitude of said value for said strike.

23. The method of claim 22 wherein said harmony includes at least one of a major triad and a minor triad.

24. A system for musical sonification comprising:

a sonification engine configured to receive a data stream including a series of data elements corresponding to financial trading events being monitored, said data elements including different data parameters related to a respective financial trading event, said sonification engine being configured to obtain data values for said data parameters and to convert said data values into sound parameters such that changes in said data values resulting from said trades correspond to changes in said sound parameters; and
