The ubiquitous "flexibility" warm up exercises can be extended into E major by using the "secret menu"

"Shouts of Joy, Complete Delight, yet Bickering, Short-fused, Ready to Fight."

This key is most famous for its use in Kanye West's song "Runaway," in which the piano introduction is pitched in E major. In more traditional and classical settings, however, the key is rarely used due to its difficulty to play on brass instruments. It is frequently seen in marching band contexts, typically as the ending key of a warm-up.
