Table 1

Summary of the general rules for melodic stimulus synthesis by the interactive training software. The melodies were presented acoustically to the subject, who had to remember it for 4 seconds and then immediately replay it on a piano keyboard. The 'level' l (left column) is an arbitrary measure of the level of complexity the subject is able to reproduce properly and therefore a measure of actual skill, making it possible to automatically adjust the task difficulty during practice. The table specifies how the parameters pitch range, number of beats (crotchets), number of additional quavers and tempo (bpm) depend on the given level.
