The first miniature of this cycle – Impromptu – has the program names Le Sabbat. The creation of this
fantastic musical image of the night gathering and the witches’ dances, which take place during the Coven,
assist not only by the dance basis of the theme and a repetition of melodic turns, but also by the chosen
tempo mark Allegro furioso, which immediately sets the mood for a frantic, rapid movement. The
Impromptu is written in a rounded binary form. The first section consists of a period of repeated
construction of two sentences. The main theme of Impromptu has a mysterious and fantastical character.
The musical image of the witches’ Coven is created by the use of chromaticism in small connections-
transitions from one sentence to the next, accented chords, which fall on the third beats of measures,
short appoggiaturas, which form minor second intervals to the upper notes of the chords to which they
belong, creating a tense, dissonant sound. Such a compositional decision evokes a creative analogy with
another musical embodiment of the Coven, presented in the Fifth Movement of The Symphonie
fantastique by H. Berlioz, which was written in 1830. We will recall that in this movement, during the
transformation of the beloved’s theme, H. Berlioz, in addition to the timbre of the clarinet-piccolo, uses
numerous flams which also decorate the melodic line with the dissonant sound of the minor second
interval.
Another composer’s find, striking in the context of the piece’s program, is the repetition of both the
rhythmic and melodic pattern within the phrase, as well as the actual form of the first section of the
Impromptu, which is a period of repeated structure from two sentences. This gives the theme some
uniformity and creates a peculiar effect, which helps to paint in the imagination a picture of repeated
repetition of certain magical utterances by the participants of the Coven.
The middle section of Impromptu focuses on the development of the previous theme, however, the
composer actively uses deviations in other keys (C major, C minor, E-flat major), which gives this part the
outlines of development. In the third section, the main theme of the piece is presented with some
changes. At the beginning of the section, there is no sf on the chords of the third beat as well as a sharp
staccato, which is here replaced by a regular staccato. However, in the future, all the defined elements of
the musical language appear in the form in which they were used in the first section. The considered
miniature is completed by a small codetta, which is based on the repeated several times final cadence
harmony T6 – S5/3 – II7 – D4/3 – T5/3. In the rhythmic relation this codetta is based on repeating the
fundamental to this piece rhythmic formula: two sixteenths-eighth under one beam and accented eighth
with a short appoggiatura that is fundamental to this piece.
The second piece, Caprice a la Boleros, like Impromptu: Le Sabbat, has an understated virtuoso character,
as evidenced in particular by the Presto tempo marking. Caprice, unlike the previous work, is written in a
ternary form with moving extreme sections and a lyrical middle. A feature of its dramaturgy’s construction
is the use of the parallel keys (E minor, E major), which alternate several times during the miniature. Such
an idea contributes to a more vivid comparison of the sections of the miniature, and emphasizes the
transformation of the main minor theme in the major coda.
The appearance of the main theme of Caprice a la Boleros is preceded by a small introduction of a toccata
character, in which the richness of the dynamic nuances involved attracts attention, because within 12
bars there must be a transition from pp to a significant crescendo. The transition from the introduction to
the exposure of the main theme of the piece is expressed by the composer with bright sf on the last note
