Extraordinary – Beethoven’s 9th Symphony Review

Astonishingly clever. For anyone who loves the 9th., the app is a delight. For any student of classical music the app is essential. It reveals the genius in the music; it lets the average person understand the music in new ways. With high-quality headphones (I use Bose noise-cancelling h-phones) it's rapturous.
