An ad for a bugle. No mention of the key that it's in?

"Love, Clear Conscience, Hopeful Aspirations for the future and a better world. Optimistic and able to take control in order to ensure peace."

The single most common key in band, especially in lower-skill ensembles. The key is ridiculously easy to play in for brass instruments, with the most important notes all being played with no valves pressed. Bugles are pitched in this key.
