Beethoven's 9th Symphony (free plus in-app purchases) is an epic iPad app that lets you explore one of the greatest symphonies ever written in a unique, compelling way. Classical music lovers will definitely want to check it out.
Beethoven's 9th Symphony uses every trick in the multimedia tool box. For starters, you can listen to four different performances of the work, taken from the well-known DGG catalog. As you listen, follow along with the the score in real time. The original manuscript displays each page as the music plays, but with modern notation.
An interesting feature called the "BeatMap" offers an overhead view of the orchestra, complete with symbols of the various instruments that glow as they are played.
The app also features several interviews, both contemporary and historic, with notable people like Leonard Bernstein and Gustavo Dudamel.
The four included performances date from 1962, with the most recent from 1992 played with period instruments. The Leonard Bernstein 1979 recording contains video of the performance, that you can watch in full-screen mode. It's interesting to compare the four concerts, and you can instantly switch between them, hearing how recording technology has advanced, and how performances differ. Having the four concerts in sync for comparison is unique and valuable.
This app is a great experience for adults and young musicians. I can't think of a better way to share this musical treasure in such depth.
