I am a clarinettist so I am a little embarrassed to need to ask this. I have not played the bass clarinet. I am looking at a miniature score of Stravinsky's The Rite of Spring (Dover Miniature Scores).

The Instrumentation page gives this (for the clarinets):

Clarinetto piccolo (D, Es)

3 Clarinetti (B, A) (Cl. II = Cl. b. II)

Clarinetto basso (B) (= Cl. IV)

This appears to be Italian but with German notes.

Small Clarinet (D, E♭)

3 Clarinets (B♭, A)(Cl. II = Bass Cl.II)

Bass Clarinet (B♭) (= Cl. IV)

So, we need 5 players: one dedicated to the small clarinet but they need both a D and an E♭ (I have seen an E♭ clarinet but never a D); 3 players with a B♭ and an A, the second also needs a bass; one player dedicated to the bass.

Now, another puzzle: towards the end of The Ritual Action of the Ancestors, we have two bass clarinets playing. The second part is written in the bass clef and the first switches to the bass clef at bar 143. I thought that the bass clarinet was a transposing instrument (down a 9th) and would be written in the treble clef. As a player, how would I interpret the bass clef? Would I now consider my instrument as only transposing by a second?

In this case, your intuition is correct: when the bass clarinet is written in the bass clef, it now only transposes by a major second instead of by a major ninth.

Transposing by a major ninth (i.e., written in treble clef) is far more common so as to allow the player to use the same fingerings as they do when playing the standard clarinet. But this bass-clef notation does occasionally appear.

But buckle up.

To make matters more confusing, the transposition level isn't fully standardized when the score briefly changes to treble clef. In the German style, the treble-clef notation is still only transposed by a major second. In the Russian style, however, treble-clef notation reverts to the standard major-ninth transposition.

Confused yet? But it gets even better: some Italian scores write the bass clarinet in bass clef but continue to transpose it by a major ninth (!).

In practice, it's best to remember the four traditions of bass-clarinet notation:

1. The standard (French) style, always written in treble clef transposed by major ninth;


2. the German style, in which all is transposed by major second;


3. the Russian style, in which treble-clef notation transposes by major ninth but bass-clef notation transposes by major second;


4. and the Italian style, in which all is transposed by major ninth (treble clef and bass clef).
