In 1993 Rauscher et al.1 made the surprising claim that, after listening to Mozart's sonata for two pianos (K448) for 10 minutes, normal subjects showed significantly better spatial reasoning skills than after periods of listening to relaxation instructions designed to lower blood pressure or silence. The mean spatial IQ scores were 8 and 9 points higher after listening to the music than in the other two conditions. The enhancing effect did not extend beyond 10-15 minutes. These results proved controversial. Some investigators were unable to reproduce the findings2,3,4 but others confirmed that listening to Mozart's sonata K448 produced a small increase in spatial-temporal performance,…A more impressive indication of a Mozart effect is to be seen in epilepsy. In 23 of 29 patients with focal discharges or bursts of generalized spike and wave complexes who listened to the Mozart piano sonata K448 there was a significant decrease in epileptiform activity
