i'll describe it thus:
- it's instrumental, with the melody played on violin, i think
- quite chirpy and upbeat but classical
- used loads in TV programmes when someone's busying around doing housework in a 50s housewife fashion
- for those of you who are music-theory-minded - the first eight notes are fairly staccato quavers (is that the term for half a beat?) - notes 1,2 and 3 on the name (quite high) pitch and the fourth note an octave below, then repeat pattern for notes 5,6,7 and 8.
