Few rational people could disagree with most of what Rosalyn says on ornamentation. But a few things - some of more gravity than others - remain under strict scrutiny. Prime amongst those is her view that ornaments (especially trills) should be played in a strictly metrical manner. Indeed this is one of those aspects of her performance that make this music sound so
mechanical, despite her attempts to mask this through the application of dynamics (in an attempt to divert the listener's mind away from rhythm towards emotion).
Her view that ornaments should be measured in this way seems merely to be a symptom of a much more serious misunderstanding of Bach's approach to melody and ornamentation. It shows a basic failure to understand that
most of Bach's written notations already embody the required ornamentation - fully written out! There is thus a subtle distinction between two kinds of ornaments (essentially similar, but designed for different purposes):
a) those which, since they are fully notated, must be performed exactly in the manner prescribed by the composer, and
b) those which, because they are indicated by the use of a symbol, are intended to be played at the discretion of the
performer (i.e. at the speed, rhythm and incision that the
performer judges at that moment to be appropriate to the style, mood and ethos "of the moment")
Those under a) require skill rather than taste, while those under b) not only require skill
but also taste.
As an example of what is involved here, we can again look at the opening of the C Minor Trio Sonata previously mentioned (above). In the following example, the first stave shows what Bach actually wrote, while the second stave presents the same music with
all the ornaments given as symbols:
Now it can be seen that some of the ornaments have been written out in full, and therefore remain strictly under the rhythmic control of the composer. (Indeed, had they not been so, their performance might have been very different, despite the note-pitches remaining the same). While there is no less clarity in these cases as to pitch, there is now absolute and complete clarity with regard to the intended rhythm.
Those ornaments in the second stave that remain identical with those in the first are very different - these are now to be interpreted and realised
entirely by the performer. The question is: how?
Bach left a brief table of ornaments as follows:
Being
notated, they have to make grammatical sense (as they do). But this does not necessarily mean that they represent anything more than a mere
pattern to be followed. They are all "quick", they all "commence on the main beat", some of them use upper notes, some lower, some both, some have lower-note terminations, others do not etc. etc......
Now the main point seems to be that where a
symbol is used (as opposed to full notation) it is up to the performer (only) to make a judgement about speed, regularity and taste that he/she (alone) judges to be appropriate - within the framework of the actual
pattern specified by the symbol.
It therefore seems to me that a listener should easily be able to understand which ornaments are the ones Bach has bothered to notate in full, and which others are those that - having been prompted by a symbol - are the ones entirely under the control of the player's judgement.
The problem with playing everything strictly "in time" is that this distinction is lost; there is no feeling that a performer is exercising freedom, spontaneity and taste. Everything sounds just as though it has all been laboriously written out in full by a boring and pedantic composer. Performances thereby sound mechanical, and the music becomes stereotypical and predictable.
Furthermore, when performers such as Koopman add further complex layers of mechanical ornamentations (not indicated even by symbols) to those which are already fully notated within the musical line, the whole thing begins to sound like a cacophonous jumble of nervous twitches that begin to destroy the melodic and harmonic clarity so cleverly invented by the composer. More importantly, it also shows a fundamental
misunderstanding of Bach's floridly ornamental style that is there from the start. This style is already a great advancement upon the melodic writing of earlier composers (who were happy to leave most of the frills within the hands of the performers).
