- Samba Em Preludio
- Context
- Bossa Nova, which takes the rich and complex harmonies of American Jazz and fuses it with the rhythm of Brazilian Samba.
- Lyrics in Portuguese
- Resources
- Female voice in a low tessitura
- The acoustic bass guitar features broken chords, double stopping, scale patterns and ornaments, such as a mordent in bar 1.
- Harmony
- The chords are complex as they are based on the rich harmonies of cool American Jazz.
- Chord extensions are used, along with chromatic chords, like the diminished 7th in bar 33.
- Many chords have extensions and chromatic alterations, typical of cool jazz.
- An extended chord (usually an 11th) would be usually used to end a jazz piece. Here the final chord is labelled Bm13, though is actually Bm#13 as the 13th is G#. The B in the bass is the tonic, but this soon dies away, leaving a shimmering discord and deliberately avoiding any sense of finality.
- Texture
- The texture in bars 1-3 is monophonic, apart from some two double stops.
- Most of the piece is homophonic, although the combination of two independent lines in bars 88-103 is contrapuntal.
- Melody
- The first or second note of every phrase falls by a step, creating a free downward sequence. This, accompanied with the low tessitura and minor key, create a sad mood, which is designed to portray the melancholy lyrics.
- Melody B is almost entirely conjunct.
- Syllabic word setting.
- Metre, Tempo and Rhythm
- The song is in simple quadruple time. The 5/4 in bar 3 is just a way of expressing the free tempo.
- The first three bars have an improvisatory character, achieved through a rubato (tiny fluctuations in tempo for an expressive effect)
- Frequent use of triplets and syncopation.
- Use of cross rhythm, which is when two rhythmic patterns that conflict with each other occur simultaneously.
- Tonality
- B minor with no modulations, although there are many chromatic notes.
