Mozart (, an educational game for music students and enthusiasts, has been upgraded to version 2.0, adding support for Mac OS X 10.7 (“Lion”).

During the game notes stream from the left to the right and have to be identified with one of the six provided instruments. The problem is that there are not only notes to deal with, but also all sorts of other entities that may explode, shift places or change the key signatures around for no reason at all.

There are two basic instruments where either letters like C, D, E or tone syllables like Do, Re, Mi are assigned. Four advanced input instruments– bass, guitar, mandolin and piano — are also available.

Mozart 2.0 makes a distinction between basic and advanced instruments. Advanced instruments are those based on real instruments like guitar or piano. These instruments now evaluate octaves (i.e. middle c will require a different input than c an octave higher). Additionally instrument positions come into play. The guitar instrument, for example, will move up to higher positions as the game level increases.

Yet another new feature for advanced instruments are accidentals. These are introduced gradually and include all base accidentals as well as double-flats and double-sharps in the higher levels.

Mozart 2.0 requires Mac OS 10.6.6 or later. It costs US$12.99 and is available worldwide exclusively through the Mac App Store in the Music category. Educational discounts as well as a limited number of teacher copies are available.
