This is a beautiful Sarabande that proceeds almost entirely in two voices. While this is a rough analysis, this Sarabande can be understood as 1+1+2. That is, it progresses in an order of 1 measure, 1 measure, and 2 measures (with exceptions in the latter half).

Measures 1 and 2 are not strictly a sequence, but they share similar melodic patterns. I believe measure 2 has a higher tension than measure 1. Then, measures 3-4 form a single phrase, and these two measures should be considered as one unit. Within measures 3-4, measure 3 has the highest tension, which then resolves in measure 4, but they should be performed as a single entity.

Next, measures 5 and 6 can be called a sequence, and these also progress in single-measure units, while measures 7-8 should be considered as a single unit of two measures.

Keeping this order in mind will make performance much easier. In the latter half, from measure 17, this order breaks down, and sequences occur consecutively. However, the piece can fundamentally be neatly divided using the 1+1+2 segmentation, so please apply appropriate dynamics and other expressive elements accordingly.
