Usage: sing (song), sing stop [to stop singing], sing [to show your current song/voice condition]
Skilled minstrels are able to use the power of their voice to perform
various effects. The most basic of these provide amusement on a journey,
allowing a small party of adventurers to travel farther and otherwise exert
themselves more than they would be usually able. The exact effect varies on
the tune sung - more powerful songs require not only more experience, but a
greater expertise in the art of singing as well, for the ballads of the
greatest power are not to be sung by the amateur vocalist.
The power of each song increases with the bard's level. Singing invariably parches the musician's throat. More powerful songs will parch a bard's throat faster than weaker ones, but the more skilled a bard is at a certain tune, the less exhausting that particular tune will be to him or her.
