Congratulations to German Ruiz-Marcos on successfully completing his viva voce examination for his PhD thesis entitled ‘Tension-driven Automatic Music Generation’. The research concerns I using purely structural harmonic means to control tension on demand in real -time (e.g. for video games) in music that has coherent long term harmonic structure. His examiners were Colin Johnson (University of Nottingham) and Ben Winters (FASS). Congratulations to German and to his supervisors Robin Laney and Alistair Willis.
