- A contour-based walking-bass algorithmPublication . Dias, Rui; Guedes, CarlosThis paper describes a contour-based algorithm for the real- time automatic generation of jazz walking bass lines, fol- lowing a given harmonic progression. A brief description of the walking bass procedure will be presented, and also a brief survey on some common implementations and tech- niques. This algorithm was implemented in the Max/MSP graphi- cal programming environment.
- A computer-mediated interface for jazz piano compingPublication . Dias, Rui; Guedes, Carlos; Marques, TelmoThis paper presents a dynamic interface and voicing algo- rithm for real-time performance of jazz piano comping. Starting with a given song with a predefined harmonic progression, the algorithm calculates and maps an array of chord voicings to a virtual piano keyboard that can be played in real-time with any physical multi-touch input device like an iPad or computer keyboard. By taking care of the note selection for the voicings, the interface pro- vides a simplified and intuitive way to play sophisticated voicings, while leaving the control over the performance aspects like timing, register, wideness and density to the user.
