Eine kleine nachtmusik

Ah, the bracing triadic sonorities of the beloved eine kleine.

Follow these activities and complete what you don't get done in class for homework.

Get the score here.

1. Read your textbook and research the piece on the web. What genre is it? What is it scored for? Where, when and for whom would it most likely have been heard? What does the title mean?

2. Use the web to find definitions and usual characteristics of the following subsections of the sonata-allegro form, and what usually happens in that section (in terms of melody, tonality, modulations, texture, mood etc):

Exposition:
First subject group (first theme)
Transition
Second group
Closing theme/codetta
Development:
Development
Retransition
Recapitulation - (which parts are different from the exposition? how?)
First subject group (first theme)
Transition
Second group
Closing theme/codetta
Coda


3. Log in to the Enjoyment of Music site and view the graphic explanation of Sonata Form in Eine Kleine Nachtmusik. Label each of the above sections in your score of movement 1.

4. Divide the piece into 6 (Annabelle: First subject; Emma: transition; Indiana: second group/codetta; Jordan: development (1st part); Lucy: retransition; and Sabrina: recapitulation) in a couple of paragraphs, compare your section with the usual features of that section within sonata form. Look at Mozart's use of tonality, contrast, development techniques, melodic structure and texture, and the character of the melody.
Type your answers up so we can cut and paste them straight into the blog here for all of you to refer to later.

Transition - Emma
Mozart's use of tonality, contrast, development techniques, melodic structure and texture, and the character of the melody.
Overall the transition in Eine Kleine Nachtmusik is very typical of that within a usual sonata form. The transition uses a very direct modulation. It explores new chords (such as C# diminished, B minor…) and introduces some new material to create a brief developmental section but mainly alters between A7 and D. The C#’s prepare us for the new key change to the dominant key. The transition goes on for 10 bars where the modulation is extremely abrupt. Thick texture is created through the use of repeated quavers/semi-quavers and double stops (eg. In violia part from bar 22). The sudden bursts of sforzandos and the overall crescendo of the transition heighten the intensity and indicate that change is about to happen. These features are all characteristic of a typical transition section within a sonata form.
Development section - Lucy

Tonality:
The development starts in the same key as the exposition ended however The sense of key is destabilised through the use of keys less closely related to the tonic with the use of chromatic notes and also by passing through keys quickly rather than settling in them. The section typically ends by dwelling on a dominant chord of the original tonic key.

Contrast:
Whole piece:
Contrast is seen through the snippets of the different themes taken from the exposition – first subject and the codetta from the exposition are developed. Also, the relatively fast key changes create a different sound to the piece that the listener has not experienced yet.

Within the development:
Dynamic changes and mood changes are contrasting features i.e. from loud and triadic to soft, light and melody in steps.

Development techniques:
Motifs of themes from exposition being developed as well as in Eine Kleine, the descending sequences with chromatic notes

Melodic Structure:
The development starts with thematic material from the first subject of the exposition, in this piece; the codetta theme is also used and developed. During the development of the codetta theme, we reach the retransition (the chromatic ascend and sustained high note in violins with the sequenced descend of the middle range strings, an overall contrary motion feel), which will ultimately take us to the recapitulation.

Texture:
The texture of the development in this piece changes due to the different themes. For example, the first subject is explored first. This triadic moving theme is pompous and heavy but very thick in texture in comparison to the codetta subject, which is second. The codetta subject is softer in dynamics and with the use of more notes (no rests) the texture is still visibly thick, but audibly, it is much thinner than the first subjects theme.

Character of melody:
As mentioned in previous paragraphs, the development consists of the first subjects theme and the codetta theme. These two thematic ideas are very different to each other, hence the character of the melody contrasting.

In the firs subject theme, the melodic character is more of a strong, confident sound, whereas the codetta theme character is more ‘fairy’ like and graceful.





5. Apart from the use of sonata form, what musical features make Eine Kleine Nachtmusik representative of the Classical Period? List at least 10 points across all concepts.

Why is Eine Kleine Nachtmusik part of the classical period? - according to Lucy
1.      Contrasts in moods
2.      Different, more flexible rhythms i.e. use of syncopation bar 24-25
3.      Melodies are tuneful and easy to remember, more thematic
4.      Gradual dynamic changes are used i.e. crescendos and decrescendos
5.      No basso continuo
6.      Instrumentation – typical string orchestra
7.      Homophonic texture
8.      Predominantly triadic chord structures with occasional sevenths
9.      Clearly defined musical phrases with contrasting themes
10. Diatonic harmony was more typical than chromatic harmony
according to Emma
• Diatonic and simple melodies
• Use of consistent rhythms
• Triadic harmony
• There is no basso continuo
• Homophonic texture
• Use of scalic patterns
• Use of gradual dynamics (crescendos, diminuendos, swells)
• String quintet typical of Classical Period
• Fexible pulse
• Contrast of mood and themes

Introducing The Classical Period

Compare these two examples of Baroque and Classical music:



Compare: harmony; melody; instrumentation; texture; form; tonality; phrase structure; dynamics; articulation; ornamentation; mood in general (expression); use of contrast and variety

Do this basic drag and drop exercise comparing the two periods.
http://www.wwnorton.com/college/music/enjoyment-of-music11/complete/ch/prelude03/era-transitions.aspx

Read your textbook pp192-196.

1. Summarise the important political and social changes that occurred in Europe during the Classical Period.(pp192-194)
2. Who are the four famous composers of the Viennese School?
3. Summarise the elements of classical music style (p195).
4. Who employed classical composers and where were their works performed?
5. How did women's role in musical life change in this period?
NB I must apologise for my inadvertent choice of performers in the Mozart video above - I don't usually listen to this orchestra for these non-musical reasons!
6. How are Classical ideas reflected in late 18th Century music?

Read pp197-204

7. What were the usual characteristics of each movement of a four-movement symphony, string quartet, sonata or (three movement) concerto?
8. What are the 3 main sections of a sonata-form movement?
9. How could you compare sonata form to the structure of a novel or play?

Bach Brandenburg no 5


Get the score for this piece here.

1. Outline the standard structure and features of the Baroque Concerto and the Concerto Grosso.
Ripieno - full orchestra; Concertino - group of soloists (concerto grosso); soloist or two soloists (concerto)
Structure:
Ritornello in full by ripieno, tonic key - solo (or concertino) episodes alternating with partial ritornello statements in other keys - longer episode/cadenza - ritornello reappears in full, in tonic key

2. Listen to the "Naxos Classics Explained" discussion of this piece and note the motifs used. Make a list of the devices Bach uses to develop his motifs.
Fragmentation into motifs; melodic alteration; augmentation; inversion; extension; stretto; imitation; sequence; contrapuntal treatment; fragments used as accompaniment figures; decoration; rhythmic alteration; inverted pedal notes
3. As a class, do a concept analysis (excluding structure - you've already done that) of the first two minutes, for homework. Choose from: Pitch; Duration; Texture; Tone Colour; Dynamics and Expressive Techniques.
Here are some starter aspects to discuss:

Pitch, by Indiana: Tonality - key, and modulations? D major - modulations to A (dominant) and Bm (relative minor) - later to F# minor (mediant) - long dominant prolongation in cadenza, return to tonic Harmony - chords used? Diatonic triads in root position and 1st inversion, and sevenths - emphasis on I and V in ritornello; some suspensions in episodes; applied dominant chords leading to modulations Harmonic rhythm? varied: slow at first, then speeding up in ritornello; usually two chords per bar
patterns (circle of fifths, cadences etc)? Circle of fifths used to modulate to V, bars 14-18 (A-D-G#dim-C#m-F#m-Bm - E7 - A) - perfect cadences used at end of ritornello, and at modulations Melody: ritornello is an unpredictable mixture of rising and falling scales, arpeggios and complex, irregular semiquaver patterns, over a wide range. sequence? used extensively in episodes, (such as over the circle of fifths section mentioned above) as well as in sections of the ritornello (eg sighing motif bar3-4) decoration? trills added by performers at cadences, written in decoration common as well, like the rising triplet pattern other devices? Motivic development? many devices used in episodes, eg augmentation and inversion, decoration (bars 11-12), extension and inverted pedal (harpsichord left hand bars 14-15) Range of melody? broad in ritornello; narrower ranges used in solo episodes at first, although solo harpsichord explores very wide range Overall pitch range (between lowest and highest instruments)? about 4 octaves

Duration: metre? 2/2 (simple duple) - strong pulse throughout
tempo? Allegro (fast) as usual for 1st movement - tempo does not change as is usual for Baroque music
rhythmic ideas and motifs? The whole piece is constructed from rhythmic motifs extracted from the opening ritornello - eg bar 7, bar 9; the three note upbeat motif, the semiquaver scale motif, etc - these are recombined and used in complex polyphony after the opening homophonic ritornello
regular or irregular rhythms? Regular, predictable rhythms in ritornello, but combined with irregular phraselengths; more unpredictable combinations of rhythmic patterns in episodes, but continuing to emphasise strong pulse and accents on beats 1 and 2 of each 2/2 bar;- some syncopation used (suspensions) and dotted note ideas at cadences; augmentation, decoration, fragmentation of themes and motifs, cross rhythms 
use of homorhythm/rhythmic unison? ritornello has rhythmic unison at some points with semiquavers to connect phrases (eg bar 5), and a clear homophonic texture, but episodes have varied, faster rhythms in upper parts combined with steady quavers in bass (walking bass). At one point there is a cross rhythm on a small scale with triplets against quavers (bar 14). (EMMA)

Texture (ANNABELLE): Polyphony/homophony? Homophonic in ritornello, polyphonic in episodes
How layers are combined in counterpoint? Contrasts in density of the texture? Relationships between layers (eg imitation, antiphony, homorhythm, etc)? Changing roles of instruments?
Ritornello, bar 1-8:
3 layers - melody - ripieno violins + solo violin;
harmony line (in rhythmic unison with bass) - viola;
bass line - double bass, cello and basso continuo (adds chords to bass line according to figured bass)
Melody and bass often in contrary motion to each other
Bar 9 - first solo for concertino group (flute, violin, harpsichord) on their own; bar 10 - interrupted by ripieno (full orchestra) with ritornello fragment
Bar 14 - thin texture as before - solo episode with only concertino group - imitation between violin and flute; harpsichord independent
Bar 19 - Contrast with only ripieno playing semiquaver arpeggio motif
Bar 21 - Concertino episode again - suspensions between flute and violin
Bar 32 - ornamented sequence and suspensions between flute and violin - ornate semiquaver figures in harpsichord RH with LH bassline - brief interruptions by ripieno throughout this section with fragments of the ritornello before a longer ripieno statement of ritornello in new key of B minor

Tone Colour: Instrumentation: concertino group (soloists): violin, (transverse) flute, harpsichord
ripieno (orchestra): violins, violas, cello, double bass, continuo harpsichord (doubles as continuo during ritornellos, as well as soloist in episodes)

In some recordings authentic Baroque instruments are used: gut strings, shorter bows, wooden flutes, harpsichord; these are played without vibrato, and have different sounds: the gut strings are softer, and warmer sounding, and the wooden flute has a light, airy sound different to a modern flute.

The softer dynamic of the flute means that it often plays in a higher register to be heard when it is playing with the full orchestra, but mainly plays in solo episodes with a thinner texture.

The harpsichord's lack of dynamic control means that it often adds extra arpeggiation and thicker chords to be heard during forte ritornello sections, and its lack of sustained sound means that it often plays semiquaver patterns and trills to sustain the sound. The virtuosity of the solo harpsichord writing is unique for the time, and explores the full range of the harpsichord (smaller than a modern piano). Its solo sections are still mainly when the ripieno isn't playing, because the harpsichord is a fairly soft instrument. The harpsichord has a ringing, thin, metallic sound owing to its playing technique (the strings are plucked, instead of hit with hammers). Two manuals (keyboards) are used.

No special instrumental techniques are required - no double stops, pizzicato or other special techniques.

Contrasts of tone colour occur throughout as the heavier sound of the ripieno orchestra interjects with solo sections with the lighter, brighter tone colours of flute, harpsichord and solo violin. (JORDAN)

Dynamics and Expressive Techniques: are dynamics indicated? yes, piano ,pianissimo and forte indicated in ripieno at some places (eg bar 10, 19, 21). Pianissimo used when soloists need to be heard above orchestra. Sudden contrasts in dynamics (terrace dynamics) are used, not crescendos.
Listen to the recording: where are dynamics used? Ripieno (tutti) sections tend to be loud (eg bar 1). Dynamics also used within phrases (eg swells on suspensions).
What sorts of ornaments are added and where? Trills usually added at cadence points in melody (eg bar 8) - sometimes written in (tr), sometimes added by performer. Other decorations (eg triplet figure in bar 10) are written in by composer here.
