Back in 1988 I published one of the
earliest articles on the alignment of translations with their originals (see
Sources below). I was not the only one to think of it about that time but I did
have one distinction: I proposed a term for it, namely bitext. More precisely bitext
was defined as
“bilingual hypertext stored in such a way that each retrievable segment consists of a segment in one language linked to a segment in the other language which has the same meaning.”
According to
the natural translation hypothesis (NTH) and some semioticians, language translating is not a
basic human competence but a specialisation of a more general competence that
in NTH we call conversion. Conversion is the ability to transform any form of
expression of ideas and sentiments into any other form and moreover to conduct
operations on it, such as summarising, during the conversion. Since conversion
ability is universal, it is predictable that there are other forms of
expression that can be organised in a way analogous to bitext. One of them is
music.
Music in
this post is shorthand for western classical music. That kind of music has been recorded for
centuries in a code or notation with a rich vocabulary of symbols like breves
and crotchets augmented with a few natural language words, mostly Italian, and
a syntax displayed on staves for joining them. We will refer to it here simply as
notation. Notation offers an advantage over the natural language wording of
bitext. Whereas language wording has to be chunked into convenient translation unit segments by complicated computing, music notation already
has its chunking prescribed into units called bars.
These days conversion from notation to MIDI sound in the form of a MIDI file can be performed automatically by software like ScanScore (see below); moreover ScanScore is reversible. But in this post we are concerned only with human conversion.
The human conversion from notation
to sound is not direct. First the notation must be perceived and decoded. Then,
more important, it must be converted to muscular code. This code directs the
performer’s fingers, lips, feet, etc., and vocal tract in the case of singers.
There’s a developmental progression in which the conversion begins consciously
but becomes internalised and intuitive with practice. Here’s Werner Goeble’s description
of how it works in the case of pianists:
“Pianists achieve extreme levels of virtuosity on their instrument, requiring a combination of talent and decade-long continuous and deliberate practice, training, and experience. As with all musical behaviors, body movements in piano performance are goal directed, aiming at producing intended sounds with utmost precision and accuracy in expressive parameters such as timing, dynamics, timbre, and articulation. Body movements in piano performance may also serve communicative purposes such as to express emotional states or to coordinate with co-performers. Pianists control the timing and chain of velocities of the individual piano hammers by varying the forces applied to the piano key surfaces, as well as to the three pedals through their feet. The key forces are accomplished by coordinating the kinematic chain from their shoulders to the fingertips aligned with feet movements to manipulate the pedals. As kinematic properties such as finger velocity covary with performance parameters (tempo, dynamics, etc.), pianists have to stabilize several parameters of movement kinematics and musical expression simultaneously. The intrinsic way the fingers arrive at the piano key surface, referred to as piano touch (i.e., pressing versus striking a piano key), yields different tactile and other sensory percepts to the pianists themselves and the audiences alike, making this parameter an important one in accomplished piano performance.”
Finally the music arrives at the outcome of the chain of conversions as structured sound. Note that music is not just sound but structured sound. That’s the other half of bi-music. We need to have it in a stable form that can be recorded, stored and processed. One such medium is MIDI files but there are others.
So now we are ready to offer a definition of
bi-music. It would be as follows:
Bi-music is music in standard music notation and chunked into bars, coupled with a MIDI or other sound recording of the same music and stored in such a way that retrieving any bar of the notation automatically retrieves also the corresponding MIDI or similar segment; or vice versa.
Would it be of any practical use? Perhaps more to
musicologists and copyright lawyers than to musicians. However, when bitext was
introduced, though it had a practical purpose it was not immediately obvious
how very useful it would be.
