I had some question about the Q: tempo line in ABC. Here's the official word, from ABC Standard V1.6

Q - tempo; can be used to specify the notes per minute, e.g. if the default note length is an eighth note then Q:120 or Q:C=120 is 120 eighth notes per minute. Similarly Q:C3=40 would be 40 dotted quarter notes per minute. An absolute tempo may also be set, e.g. Q:1/8=120 is also 120 eighth notes per minute, irrespective of the default note length.

• Note that there are no spaces after the Q:.
• The recommended order is: X: T: M: L: K:
• If you use Q: to set the tempo it is best between L: and K:
• Q: is optional, and the only required headings are X:(tune no), T:(title), M:(meter), and K:(key).
• For further information about ABC, consult the ABC Home Page and the Mudcat ABC Tune Guide.

Remember that if you post lyrics or ABC tunes at Mudcat, you need to include <br> line breaks on every line.
