themes have been adapted.

149. A _rondo_ is an instrumental composition (in homophonic style) in
which a certain theme appears several times almost always in the same
form (_i.e._, not thematically varied), the repetitions of this theme
being separated by contrasting material.

The _rondo_ is the oldest of the larger monophonic forms and has been
used in many different ways, but perhaps its most characteristic
construction is as follows: (1) Principal subject; (2) second subject in
dominant key; (3) principal subject; (4) third subject; (5) first
subject again; (6) second subject, in _tonic key_; (7) coda (or ending).

The student should note particularly the problem of repetition and
contrast (mentioned in Sec. 134) as here worked out, as the rondo was
the first monophonic form in which this matter was at all satisfactorily
solved, and its construction is especially interesting because it is
readily seen to be one of the direct predecessors of the highest form of
all--the sonata. Examples of rondos may be found in any volume of
sonatas or sonatinas.

150. A _suite_ is a set of instrumental dances all in the same or in
nearly related keys. The first dance is usually preceded by an
introduction or prelude, and the various dances are so grouped as to
secure contrast of movement--a quick dance being usually followed by a
slower one.

The suite is interesting to students of the development of
music as being the first form _in several movements_ to be
generally adopted by composers. It retained its popularity
from the beginning of the seventeenth to the end of the
eighteenth centuries, being finally displaced by the sonata,
whose immediate predecessor it is thus seen to be.

The _suite_ was formerly written for solo instrument only (harpsichord,
clavichord, piano) but modern composers like Dvo[vr]ak, Lachner,
Moszkowski, and others have written suites for full orchestra also.

151. Among the dances commonly found in suites are the following:

_Allemande_--duple or quadruple measure.

_Bolero_--triple measure.

_Bouree_--duple or quadruple measure.

_Chaconne_--triple measure.

_Courante_--a very old dance in triple measure.

_Csardas_--Hungarian dance in duple or quadruple measure.

_Gavotte_--quadruple measure.

_Gigue_ (or _jig_)--duple measu
