Dynamics and timbre
With regard to this category, it is important to
consider the many possibilities of sudden, quick changes in
dynamics and, consequently, in timbre, when playing the
organ: subito forte or subito piano and the echo, very often
used by North German masters, i.e. in Nicolaus Bruhns’
choral fantasy Nun komm der Heiden Heiland (Bruhns and
Brunckhorst, n.d, p. 40, mm. 52–56). Besides, the swift
changes in timbre like in dialogue-imitating pieces that
are often found in French baroque organ music. Louis
Marchand’s Basse de Trompette from his Premier livre d’orgue
(Marchand, 1740) is a good example. Phenomenologically
there is no way to predict such changes, nor it is possible
to precise expectations since, unlike harmony – where
expectations may be raised thanks to the natural laws
regarding the relation between tones –, in the case
of dynamics it is not materially possible to form any
expectations. Therefore, this type of variation in dynamics
or timbre is classied as one of the origins of the absolute
surprise.
Another fundamental feature is the imitation of
sounds that are not typical for organs, like the Vogelgesang
(“bird song”) stop. This stop is based on an elaborate
construction of several pipes immersed in water (Adlung,
1931). This allows the production of a sound that imitates
bird singing. This stop is not used often and, therefore, its
sound may surprise the listener. A further example of non-
characteristic sound for an organ could be the Cymbalstern,
the rotating Christmas star, which produces the sound of
tinkling by means of several bells attached to a star that
rings when is turning (Wedgwood, 1905). Such sounds
are not typical for the organ since they are not associated
with a wind instrument. It seems appropriate to assume
that hearing these stops, the listener would experience a
contradiction with the expectation of hearing another kind
of instrument. Hence, the use of such stops may be one of
the origins of the relative surprise.
Finally, music for the organ, because of the
specicity of the instrument, may also surprise the listener
if the piece involves imitation of an instrumental ensemble.
One of the most famous examples of such imitation is
the trio. Johann Sebastian Bach’s trio sonatas for organ
BWV 525–530 (Bach, 1984) illustrate this case perfectly.
Technically-dicult pieces where the organist plays three
dierent instruments at the same time, using two manual
keyboards and the pedal keyboard. Another example could
be a melody played over a sort of sound background, as
in Tierce en taille from L. Marchand’s Premier livre d’orgue
and in Johannes Brahms’s choral prelude Herzlich tut mich
verlangen op. 122 n° 10. In all three examples, there is a
contradiction between the number of players and the
number of instruments or parts that are actually perceived.
In view of this discrepancy, it is possible to assume that the
imitation of an instrumental ensemble in organ music can
induce the emotion of relative surprise.
Thus, an analysis of dynamics and timbre leads
to argue about three possible origins of surprise: (1) the
changes in dynamics and timbre, which correspond to
absolute surprise; (2) the sounds not typical for organ, and
3) the imitation of an ensemble, producing relative surprise.
Harmony
There are two possible types of unexpected
harmonic development that could originate musical
surprise: (1) avoiding harmonic closure, and (2) original
harmonic sequences.
Harmonic closure may produce contradictions
with expectations by raising unfullled expectations in
the listener. According to some major studies in music
perception (Rosner & Namour, 1992), the most expected
cadential sequence in Western music is the authentic one
– where the V degree is followed by the I degree – and is
always perceived as the most closed. Since V is the closest
harmonic to I (if the octave dierences are not taken into
account), it is natural to remark this link because is based
on the natural laws of physics. So, hearing a cadence,
the listener normally expects that V (or, in case of plagal
cadence, IV) degree will be followed by a I degree chord.
Even more, the listener expects that this would constitute a
perceptible end of the current musical idea.
Thus, harmonic closure may be avoided by giving
preference to the deceptive cadence (for example, C.
Merulo’s Toccata undecimo detto quinto tuono, mm. 3-4) as
well as by continuing the musical idea immediately after the
cadence (for example, in J.S. Bach’s Praeludium and fugue in
e minor, BWV 548, mm. 18-19). In these cases, the listener
may experience contradiction with own expectations,
which would give rise relative surprise.
Using innovative, distinctive harmonic sequences
is the second case of harmony-related behavior. Though
cadences can elicit a sense of relative surprise, innovative
and distinctive harmonic sequences seem capable
of evoking absolute surprise. If the composer creates
harmonic sequences that do not conform to the traditional,
classical aesthetics of Western art music – culturally
aordable – canon, the listener may be confronted with a
musical phenomenon that does not provide material for
formulating precise expectations about what will come
next. The Toccata septima from Johann Ernst Eberlin’s IX
Toccate e fughe per organo (Eberlin, 1747) can illustrate
this origin of absolute surprise since the listener has no
expectations about what he perceives.
Melody
It is possible to distinguish two cases of melodical
elements that could cause surprise: the usage of accidentals
and the melodic jumps. About the accidentals, it is implied
their usage in the melodic realm without considering the
harmonical spectrum, because often they contradict the
