Take this link to a beautifully clear photo of the University of Wisconsin’s Central Javanese gamelan. Hold cursor over any instrument and it will bring up the instrument’s name. Click on any instrument and it will link you to close-up photos and instrument descriptions. Beyond the photo, the website as a whole is excellent. A very nice resource for teaching!
