brandenburg-section B(part 2)

They all play a rising scale using the separate quaver idea of the countersubject material

From bar 128, the ripieno join back into the texture and the ripieno violin plays the subject which is answered by the solo flute and violin in unison. What do the rest of the ripieno and harpsichord play at this moment?

It is still based on a rising scale but alternates between octaves. Bars 134-136 have a simple rising scale but then the F leaps down an octave before moving to G which then leaps up the octave before moving to A and so on.

At bar 136, the ripieno violin and the solo flute and violin play rising sequences. How has the countersubject changed now?

A major

At bar 148, we hear the varied subject theme again but this time in the ripieno violin and viola. What key is the music now in?

It is the relative major (up 3 semitones)

How does this new key at 148 relate to the previous key of F# minor?

A tonic pedal (now on an A in the key of A major)

What harmonic device is used throughout the first 8 bars of this section?

The harpsichord against the solo violin and flute with the violin and viola from the ripieno too.

The end of this section is created by alternating two bar sections of dialogue between which parts?

A trill (because it is the only way of holding the sound while it waits for the others to play)

What melodic device is used by the harpsichord while the other instruments have their turn in the dialogue section?

E minor

Act the start of this dialogues section (bar 155), the key moves to the dominant minor of the previous key. What is the new key?

B minor

Bach then uses a falling sequence in the harpsichord to move the music back to the opening key of the section before the extended harpsichord solo begins. What is the key of the music before the extended solo?

Canon (a canon is where the music is repeated exactly the same - in this case it is one octave apart but the letter names of the notes and the rhythms remain the same)

The opening of the extended solo in the harpsichord uses what melodic device?

Interjections or dialogue

Towards the end of the solo, other instruments become involved. How would you describe the effect they create?

2-part counterpoint

As the harpsichord moves into playing continuous triplets (from bar 193), how would you describe how the two solo instruments (violin and flute) are playing?

Stretto

The section comes to a close using full tutti texture and a fugal device called what?

B minor

What key does section B end in?

It just starts with a D major chord in the basso continuo group to state the new key. It is quite an acceptable (although unprepared key change) as D major is the relative of B minor so they can switch quite effortlessly.

How does the repeat of section A differ from the first time we hear it?
