My method consists in a preliminary study of the score together with the “particella”. It´s crucial to use your ears in a very critical way, both to identify mistakes (wrong notes, lenghts, articulation, phrasing…) and to propose solutions. In order to justify the changes, I investigate the harmonic context, the bass line, what other sections are playing (depending on the repertoire I look into one section or another), who is playing in my same octave (a dissonance at a distance of a second is harsher than one at a distance of 16th or a triple octave). With all that information I make a decision whether to make a change or not and what change to make once I decide to go for it. Once the part has been edited, it has to fit the musical context perfectly and, again, your ears will have the last word. As a precaution, never assume that the part is correct (specially in opera, and more specifically, with Kalmus editions).
To better follow the process, here´s a link to the full score (free and legal): IMSLP.
It is in bar nº3 that we encounter the first problem, as the second and fourth parts (at least in the Ricordi edition) have no accent.
My interpretation is to accent those notes in bars 3 and 4 in order to imitate the phrasing of trumpets and horns. The last two notes are played with more emphasis to prepare the choir entrance. That G in bar 5, I let it ring for four bars (plus downbeat on the fifth one) to match the ornate pedal played by winds and strings. I mute that note once the choir ceases its intervention and the strings start they diabolic 16ths.
The next beat is a mixture of the motive played by woodwinds (the 32nds are taken from them) and the rhythmic cell by the fourth basoon, trombones, oficleide and double basses (see bar 20 in the score).
Offbeats coming next have to be played very precisely, as timpani are the only instrument playing that rhythmical cell.
I like starting the roll on the A a little bit softer so I can play a crescendo to accompany the upwards scale by woodwinds and strings.
The next bars are the most problematic ones, as the notes chosen by Verdi have nothing to do with the harmonic context. The chord sequence is G9b-Cm-F9b-Bb-G7dim-Ab (see bars 31 to 36 in the score), so it´s very clear that G and D (the notes used by Verdi) create obvious dissonances.
In an E major context a G natural doesn´t match at all, so it is for this reason that I play the next roll on E natural (same note played by basoons, oficleide and double basses).
Two bars afterwards, I play A flat instead of G because that´s the harmonic context (no need to say that minor second dissonance is unacceptable).
The rest of the interventions present no problem, as they literally double the basses part.
The problem with these kind of modifications is that, if no change is made, the result is obviously dissonant but, if we edit the part, many changes have to be made.
To prove my decision I have to say that Verdi knew pedal timpani (he maybe wrote with Carlo Antonio Boracchi´s instruments in mind -he was timpanist for La Scala-), that he wrote a roll with changing notes (“Otello”, first act, six bars before letter I) and that he wrote an ascending line from B flat do D (“Requiem”, “Dies Irae”, bars 74 to 88). If Verdi wrote these changes, why he didn´t so in other parts in the “Requiem” or other of his operas? It´s surprisingly contradictory that Verdi had, at the same time, such a conservative timpani writing in some parts and such an innovative one in others in the same work
My criteria is to make Music and, if that implies changing notes, I see no problem in doing it.
In my next post I´ll write some more on this fascinating issue and, for that, I´ll use the “Sanctus” as an example.
I´d love to hear your oppinions on this subject, so any comment is welcome.
…et in Arcadia ego.
