Musical terms, tempi

For a start, an interesting experiment with mechanical metronomes: click the link
Tempi and the metronome
The tempo a piece is played on is significant for the kind of music it stands for. Therefor the tempo is written down at the beginning of a score, at least in most occasions. Often it does happen that the wanted tempo is indicated using a musical term. So it is good that we do know that Lento does mean slow, and Allegro stands for fast, but yet this does not tell us how to set the metronome. For avoiding this problem we do give a list with the most common tempo terms and the number of beats/minute they stand for. Take note that the number of beats is only an indication!
