Problem
1:
Listen to this movement from Bach's Cantata
No. 52.
Does time have an effect on the material?
Correct!
Incorrect.
The opening section is reprised exactly and in its entirety.
Time does not have an effect.
Problem
2:
Listen to the second, third and fourth movements of Earl
Kim's Now and Then. The second movement,
Thither, is reprised. Does time have an
effect?
Correct!
Incorrect.
The second movement song, Thither, is
replayed identically. Time does not have an effect.
Problem 3
Click when you hear a new section. Use the pull-down
menus to label the section. Use the prime notation if a
refrain is transformed in some way.

Solution 3
The first refrain of the A-section is literal. The only
change is that, this time, the melody is played only once
and then proceeds directly into the C-section, rendering the
connection more impulsive.
The C-section is characterized by a new, faster underlying
rhythm. When the A-section once again returns, the
accompaniment does not revert to its
earlier speed as expected. Instead, the C-section's faster
rhythm continues, blurring the
distinction between the two sections. Instead of reverting
to the original A-section, Beethoven's ending is gently
progressive.

time had an effect?

Solution 4
The first refrain of the A-section is literal and complete.
The second begins identically, but then a haunting
transformation takes place: The theme, which had been
continuous, is broken up into fragments, separated by
silences.
Time has had an effect! Where do the silences come from?
Compare the starting and stopping nature of the
A′-section with this passage from earlier in the work:
Mozart never returns to the original A-section: The
fragmented version is the last one we hear.

Has time had an effect?

Solution 5
At the first refrain, time does have an effect. The opening
rhythmic patterns return only in the lower strings,
juxtaposed against a lyrical melody in the first violin. As
the section is prolonged, the rhythmic patterns and melodic
fragments circulate among the instruments.
At the final refrain, time does not have an effect. The
ending is a literal restatement of the opening passage. It
is, however, cut short and ends unexpectedly in the middle
of a phrase. If you chose that "time does have an
effect" for this reason, then you have a valid argument.
The second half of this movement is filled with fragmentary
refrains of earlier passages. These fragments are relatively
equal in length; the final refrain of the A-section fits the
expected proportion. So, although it is abbreviated, the
final refrain is not shockingly short: The music has never
offered a complete restatement; it has taught us to expect
only excerpts. In all other respects, the final
refrain's identity is secure. That is why, in my
opinion, the listener will consider that time has not had an
effect--or has had a negligible one--at the
movement's close. Nevertheless, the movement ends
suspensively, preparing the way for the quartet to continue.

Problem
6:
Listen to the opening of Schubert’s String Quartet no. 15 in G-Major and compare it with its refrain later in the movement. Has time had an effect on the material?
Correct!
Incorrect.
Yes, time has an effect. The refrain has a very different character than the opening: It is more gentle and lyrical. Plucked sounds take the place of the aggressive chords. The dotted rhythms of the opening are smoothed out. The melody hesitates where it didn’t before and adds embellishments. All of these changes support a remarkable feature: The original version begins with a sustained G-Major triad that is replaced by a sharply accentuated g-minor chord. The refrain does the reverse: It is the minor that enters first, only to be replaced by the Major one, this time gracefully plucked! Even if the tonal contrast between Major and minor is unfamiliar or hard to hear, you won’t miss the other transformations that support this switch.
Problem
7:
Listen to the following excerpt from Dmitri Shostakovich’s String Quartet No. 7. When the reprise of the opening occurs, does time have an effect on the material?
Correct!
Incorrect.
Yes, time has an effect. In the return, the theme is mainly plucked, rather than bowed. There are sudden interjections. The rhythms are also subtly changed.
FURTHER LISTENING: Maurice Ravel's "Bolero" is a seminal example of time strengthening the material. The piece consists of the same melody repeated over and over, each time with heavier orchestration. Alvin Lucier's "I Am Sitting In A Room" is an experimental example of time weakening the material. The composer recorded himself reading a brief text. He then broadcast the recording into a room and recorded it. He took that recording, broadcast it and recorded it. As he repeated this circular process, the fidelity of the recording gradually degraded, until all that was left was the resonance frequency of the room vibrating with the rhythm of his voice.
