Abstract

The present disclosure relates to methods and devices for visualizing the rhythmic structure of musical compositions. Circular symmetry and geometric shapes are utilized to visualize representations of rhythmic structures about a central axis. In general, lower frequency rhythm instruments are represented by small geometric shapes, while relatively higher frequency instruments are represented by shapes of larger diameter. The visualizations can be presented in two or three dimensions and may incorporate the use of animation. The result is a graphical representation that is more intuitive and entertaining than traditional music notation.

Claims

1. A method for visualizing musical rhythmic structure, comprising the steps of:

(a) receiving an input representing an occurrence of a musical rhythmic event;

(b) assigning a visual representation to said input; and

(c) displaying said visual representation about a single central axis on a display;

wherein;

(1) said visual representation comprises a first substantially circular shape having a first maximum diameter if said input represents the sounding of a first rhythmic instrument;

said first rhythmic instrument having a first primary frequency;

(2) said visual representation comprises a second substantially circular shape if said input represents the sounding of a second rhythmic instrument;

said second rhythmic instrument having a second primary frequency that is higher than said first primary frequency;

said second substantially circular shape having a second maximum diameter which is greater than said first maximum diameter and a first minimum diameter which is greater than said first maximum diameter; and

(3) said visual representation comprises a third substantially circular shape if said input represents the sounding of a third rhythmic instrument;

said third rhythmic instrument having a third primary frequency that is higher than said second primary frequency;

said third substantially circular shape having a third maximum diameter which is greater than said second maximum diameter and a second minimum diameter which is greater than said second maximum diameter.

2. The method of claim 1, wherein:

(a) said visual representation is displayed two-dimensionally;

(b) said first substantially circular shape is a circle; and

(c) said second substantially circular shape is a ring.

3. The method of claim 1, wherein:

(a) said first rhythmic instrument is a bass drum; and

(b) said second rhythmic instrument is selected from the group consisting of a floor tom, a rack tom, and a snare drum.

4. The method of claim 3, wherein:

(a) said third rhythmic instrument is a cymbal.

5. The method of claim 1, wherein:

(a) said third substantially circular shape is substantially a ring;

(b) the radial thickness of said third substantially circular shape varies over the circumference of said third substantially circular shape; and

(c) said variation of said radial thickness comprises at least twenty increasing and decreasing thickness transitions.

6. The method of claim 1, further comprising the step of:

(a) animating a plurality of said visual representations about said axis as said rhythmic events occur in real time.

7. The method of claim 6, wherein:

(a) said visual representations fade into the background display color after a user-specified time.

8. The method of claim 1, wherein:

(a) said visual representation is displayed in a three-dimensional perspective view;

(b) said first substantially circular shape is a spheroid; and

(c) said second substantially circular shape is a toroid.

9. The method of claim 8, wherein:

(a) said first rhythmic instrument is a bass drum; and

(b) said second rhythmic instrument is selected from the group consisting of a floor tom, a rack tom, and a snare drum.

10. The method of claim 9, wherein:

(a) said third rhythmic instrument is a cymbal; and

(b) said third substantially circular shape is substantially a toroid.

11. The method of claim 10, wherein:

(a) the radial thickness of said third substantially circular shape is varied over the circumference of said substantially circular shape.

12. The method of claim 8, further comprising the step of:

animating a plurality of successive said visual representations along said axis as a plurality of said rhythmic events occur over time, with each visual representation first appearing at the closest perspective point to the viewer and traveling towards the farthest perspective point to the viewer.

13. The method of claim 12, wherein:

said visual representations fade into the background display color before reaching the farthest perspective point to the viewer.

14. The method of claim 8, further comprising the step of:

(a) animating a plurality of successive said visual representations along said axis as a plurality of said rhythmic events occur over time, with each visual representation first appearing at the farthest perspective point to the viewer and traveling towards the closest perspective point to the viewer.
