Tune of the Day: Sadi moma bela loza
This folk tune, whose title means “A girl planted a vine”, comes from Bulgaria. Those unaccustomed to odd rhythms could take its unevenness to be a mistake, but the tune is really in 7/8 time. The meter can be analyzed into three subgroups as slow-quick-quick or 3-2-2. Such meters in Bulgarian music can often be stretched, and some musicians play this song as 3-2-3 instead; however, Yves Moreau, who collected and taught the dance, endorses the rhythm of 7.
This is the tune used by Richard Stallman for “The Free Software Song”.
