Ostinato
In music, an ostinato is a motif or phrase, which is persistently repeated in the same musical voice. An ostinato is always a succession of equal sounds, wherein each note always has the same weight or stress. The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody in...

Buxtehude scholar Michael Belotti suggested that all three ostinato works were composed after 1690. Kerala Snyder, on the basis of the passacaglia's complex form (see below), also argues that it is a late work.

In musical notation, a bar is a segment of time defined by a given number of beats of a given duration.

Key (music)
In music theory, the term key is used in many different and sometimes contradictory ways. A common use is to speak of music as being "in" a specific key, such as in the key of C major or in the key of F-sharp. Sometimes the terms "major" or "minor" are appended, as in the key of A minor or in the...

 is exhibited in the passacaglia's intricate structure. The numbers 4 and 7 are the foundation of the entire piece. The ostinato pattern is composed of 7 notes in 4 bars, and it appears 28 times (4 × 7 = 28). There are 4 sections, each 28 bars long. The non-thematic bars (three interludes, each 3 bars long, an upbeat bar at the beginning and the last bar for the final chord) add up to 11 (4 + 7 = 11).

Reception

Philip Spitta discussed Buxtehude's work in his 1873 Bach biography, and remarked that "for beauty and importance [Buxtehude's ostinato works] take the precedence of all the works of the kind of the time, and are in the first rank of Buxtehude's compositions. [Indeed], there is no piece of music of that time known to me which surpasses it, or even approaches it, in affecting, soul-piercing intensity of expression." Spitta's opinion was shared by Johannes Brahms

. Buxtehude's passacaglia is a source of inspiration to the two central characters. The protagonist describes the piece as "seltsame, innige, in sich selbst versenkte, sich selber belauschende Musik"—"strange, intimate music which sank in itself and observed itself." Werner Breig, writing the liner for Helmut Walcha's recording of the passacaglia in 1978, called it Buxtehude's most mature work, and the pinnacle of Buxtehude's music for organ: "The reason for this may lie in the fact that it makes the most exhaustive use of the potential of the polarity of strictness and freedom. The basic theme heard unchanging in the pedal is contrasted with a complex of upper voices characterized by a positively overflowing wealth of invention."
