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
