"Eternal Mozart" automatically composes minuets (slow, triple-meter dance music) in the style of Mozart in real time and plays them on various instruments. Theoretically, it can automatically compose over 300 trillion different minuets. It allows you to pick the tempo and the number of pieces to be played from 1, 3, 60, 120, or an infinite number. It also allows you to choose the instrumentation from fortepiano, music box 1, music box 2, woodwind ensemble 1, woodwind ensemble 2, woodwind ensemble 3, harpsichord, flute and harp, or harp. Playing all the different pieces continuously would take approximately 700 million years. This app is roughly based on Mozart's KV Anh. H24,11. Use the app for background music while working or studying, or as a music box to rest or relax.
