Strathspeys are also in common time and are marked 4/4. The characteristic feature of Scottish Strathspeys is the Scotch "snap". The tempo for Strathspeys is approximately 56 on the metronome - roughly 60 seconds for 32 bars. A strathspey, which is repeated 8 times, can take 8 minutes to dance.
Traditional dances, have traditional tunes attached to them and are recognized by the tune as well as the dance. When possible the correct tunes should be used for these dances and kept exclusively for these well known dances. The music should inspire you to dance, and should be played with variations and "light and shade" to urge the dancers on to dance with great spirit.
Listen to the music, its usually chosen very carefully to add to your inspiration to dance!
