  • TECHNICAL DESCRIPTION

    Brass keys with round flat flaps, soldered. Heavy keywork. All keys on saddles. 7 keys for L-thumb.

    Basically Sellner-oboe layout.

    Angled instrument with a knee socket and a bell boot joint in Brod Baritone oboe-style. 6 lower extension notes.

    Raised key rings circular.

    Hole 6 with raised wooden insert.

    SATK (springs attached to the key).

    Bulb bell.

    Lower extension key-holes are bassoon-like, huge and function as vent-holes.

    No metal lining as far as can be seen.

  • FL ?> Faults

    Bad condition. Keys bent, pads and springs missing. Instrument kept together with wire in some places.

  • PA ?> Playing Accessories

    Bocal (not clear if original). Mahillon (R1978) Vol. II pp. 253-4 also mentions a reed.

  • UP ?> Usable Pitch

    Played with a reed TL 52.8 mm / staple 28 mm ø 5 mm / tip width 11 mm, combined with the present bocal gave as a result A=c. 440-2 Hz as far as could be tested.

  • PC ?> Performance Characteristics

    Instrument could hardly be played because of bad condition, but it is definitely an F-oboe.

  • PO ?> Previous Ownership

    Unknown. The museum acquisition date is also unclear, but most probably 1883.

  • SR ?> Specific literature Reference

    Mahillon (R1978) Vol. II pp. 253-4.

    Altenburg (1897) p. 194.

  • Remarks

    Most probably German.

     

    Mahillon (R1978) Vol. II pp. 253-4, argues that this is an experimental musical instrument (....“exagération”....“grave inconvénients”....) but not successful due to too many keys.

     

    Some sources suggest that this instrument could possibly be made by Streitwolf. The German family Streitwolf (fl 1806-1861) is reported to have made/invented English horns with extension notes. See Waterhouse (1993) pp. 389-90.

    Altenburg (1897) p. 194, comparing this very instrument with a Streitwolf E. horn (Heckel Collection, instrument with 3 lower extension notes), but without ascribing the 0975 specifically to Streitwolf, although he remarks ("…there is no name on the instrument…") that such an instrument could very well have been conceived by the mind of an inventor such as Streitwolf. Without describing the instrument in detail, Altenburg reports that he and Mr. Mahillon came to the conclusion that this kind of experiment with too many keys made the instrument rather unworkable.

     

    Rudimentary comparison of the 0975 with pictures of both the Streitwolf English horns of St Petersburg (Katalog sobranija muzykal'nych instrumentov 1972, photo section, no page number) and the Heckel Collection (see Heckel (R2000) p. 37) suggested not much resemblance to the 0975. Both Streitwolf instruments have a bass clarinet-like extension and are straight.

     

    The keywork of the 0975 is not very nice, and is entirely screwed into the instrument’s body. Therefore it is not unimaginable that this instrument was originally a 2- or 3-keyed instrument with a simple bulb bell – although hole 3 and 4 are single - to which a bell boot joint and an experimental keywork have been added over time.

    Rudimentary comparison of the 0975 with a picture of the Streitwolf angled English horn KGS-1963-0060-117 in the Zürich Bellerive museum did not give any more clarity.
