Using identifiers for triplets

[Anders Nelstrom]

Is it possible to create an identifier to save typing when triplets  
are required? For example, instead of typing:

\times 2/3 { c8 e g } \times 2/3 { c g e } c

it would be great to use:

\trip { c8 e g } \trip { c g e } c4

or such like.

I appreciate that the \times command is flexible, and I have used it  
occasionally to represent septuplets, and other oddities, but it  
feels like an awful lot of typing for the common triplet!
