When used unhyphenated, in conjunction with no other indicator of rank, the term refers to the rank just senior to that of an army captain and just below the rank of lieutenant colonel. It is considered the most junior of the field ranks. In some militaries, notably France, the rank is referred to as commandant, while in others it is known as captain-major. It is also used in some police forces and other paramilitary rank structures.

When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including general-major or major general, denoting a mid-level general officer, and sergeant major, denoting the most senior NCO of a military unit.

It can also be used with a hyphen to denote the leader of a military band such as in pipe-major or drum-major.

Johann Pachelbel ( /ˈjoʊhɑːn ˈpækəlbɛl/ or /ˈpɑːkəlbɛl/;German: [ˈjoːhan ˈpaxɛlbəl], baptised September 1, 1653 – buried March 9, 1706) was a German Baroque composer, organist and teacher, who brought the south German organ tradition to its peak. He composed a large body of sacred and secular music, and his contributions to the development of the chorale prelude and fugue have earned him a place among the most important composers of the middle Baroque era.

Pachelbel's music enjoyed enormous popularity during his lifetime; he had many pupils and his music became a model for the composers of south and central Germany. Today, Pachelbel is best known for the Canon in D, the only canon he wrote – although a true canon at the unison in three parts, it is often regarded more as a passacaglia, and it is in this mode that it has been arranged and transcribed for many different media. In addition to the canon, his most well-known works include the Chaconne in F minor, the Toccata in E minor for organ, and the Hexachordum Apollinis, a set of keyboard variations.
