Cost: $1.99

I think this app is really, really cool.  I feel that it is important to mention though that I am a music minor and a percussionist so that could add to my awe of this app.  The Visual Encyclopedia of Percussion Musical Instruments offers a detailed look at more than one hundred percussion instruments from around the world.  The encyclopedia is very easy to operate as well.  Simply touch an instrument you wish you learn more about:

The instrument will direct you to its screen.  At this screen you have several options.  You can hear one beat or one rhythm patter of the instrument.  A 360 degree view of the instrument is also available.  My favorite option is to click on the "i."  This icon directs you to information such as the instrument's origin and how to play it.

I would use this app in the classroom by having students find percussion instruments that originate from the same country.  This could help map out a musical instrument map.  I also think that students will enjoy playing all the different percussion instruments, and the students might be inspired to create their own. 

Pros:  This app contains so much knowledge for percussion instruments.  I have already used it in class and found it extrememly effective; especially for only $1.99.  This app is also very interactive, which is something I appreciate.

Cons:  Well, the app is not free.  Furthermore, the background music on the homescreen threw me off a couple of times.  Also, I do not know how relevant this app is to teachers who are not interested in teaching music.
