signature of C major, B flat clarinets are notated with a key signature of D major).
Contrariwise, but according to the same set of conventions, transposing brass
instruments (i.e. horns and trumpets) are notated without key signatures, as also are
the timpani. 56
In ŠFS and OP, the horns are notated at various points in G, E and F; in the
present reconstruction the notation has been standardised according to modern
practice, with the horns playing in F throughout. Trumpet transpositions are as in ŠFS
and OP. The clarinets likewise follow the original transpositions, except in those
cases where a quick change between instruments is unfeasible or where the notation is
clearer in the alternative transposition (A or B flat): such departures from the original
transpositions are specified in footnotes.
Horns
The full complement of four horns is used only rarely, and much of the opera is
written for just horns 1 to 3. In OP, the third and fourth horns are both copied in the
same part. The limited resources of the Brno National Theatre orchestra at the time of
the première in any case seem not to have extended beyond a trio of horns.
Occasional editorial suggestions for the additional use of all four horns are indicated
in small notes.
Trombones and tuba
As with the horns (see above), the trombone section at the Brno National Theatre around
1904 appears to have been limited to three players. The fourth part is written in the
56 ŠFS includes sporadic — and often erratic — key signatures for cor anglais and clarinets, but far less
frequently for trumpets and horns (an exception is the first page of the full score: see Fig. 2.1.)
