Throughout the Sacred Harp singing community there are several geographic areas where, over time, variations have developed in leading and singing styles. Some of this came about because in the early days, before airplanes and cars made transportation so easy, the various groups of singers were more isolated from one another. Differences in local practices in tempo and leading styles can still be seen and heard today.
Some areas love really quick tempos.
Some prefer slower tempos. Let me emphasize that the vast majority of traditional Sacred Harp singers lead in two beats to the measure. So it is with some reluctance that I write and publish this piece on leading in four beats. However, with the recent interest with singings in Hoboken, Georgia and examples in leading as done by the Woottens, I see a need to describe this technique, especially so that newcomers will have a frame of reference. I would strongly advise that you observe the local customs in any given setting before launching into 4 beats to the measure.
