The pairing of wind instruments — in this case clarinets — had been highly popular since the Baroque, and we find it, for instance, in the work of Vivaldi, Rameau, and, later, in the double concerti of Carl Stamitz and Frantisek Vincenc Kramar (Krommer).

The Czech composer Jan Zach (1699 — 1773) represents the transition from the Late Baroque to Early Classical. A considerable part of his work is church music, and the probing nature of the composer is particularly apparent here. Though he lived for a long time in Germany and frequently visited Italy, it is the purely Czech melodiousness that makes his music distinctive.

The trio sonata, which has been preserved only in manuscript copies found at the castle of Duchcov in north Bohemia, bears the title Sonata a tre Stromenti Del Sign. Giovanni Zach detto Il Boemo (cf. the Musica Antiqua Bohemica edition, 1951). This suggests that in its performance it was possible to use other instruments apart from strings, as had been the custom in trio sonatas of that time. The impetus for the arrangement for two clarinets and basso lay in the sonatas Op. 18 by Jan Krtitel Vanhal, written for this combination of instruments. The Sonata a tre Stromenti has four short movements in which a slow tempo alternates with quicker one in a basic major key, with the exception of the slower third movement, which is in a minor key. Stylistically it is a forerunner of all Vanhal's six sonatas and also allows for a comparison of the differences and connections in the musical thinking of the two composers.

In the clarinet literature Jan Krtitel Vanhal (1732—1813) is known mainly for his sonatas for piano and clarinet, whose informal movements contain suggestions of early Romanticism. The clarinet, which in the Romantic period came to enjoy its greatest efflorescence, found favour also among Czech composers who were living abroad. This is evident in the numerous chamber works using this instrument in concerts, including Vanhal's concert for clarinet and orchestra. Vanhal's life was not easy, and as one of the first independent composers he, too, was forced to conform to the performance conventions of his day. He strove to see his compositions widely played, which is why we see a frequent change of instruments here. The sonatas for piano and clarinet were, for instance, also intended for violin or viola. Stylistically Vanhal's work is not unified, and apart from influences of the Late Baroque and the Style Galant, it contains pre-Romantic elements. Regular features of Vanhal's work, however, include the attempt to achieve honest composition and the continuous presence of Czech music.

Trio Sonatas Opus 18 was published in Paris c. 1780 in two versions — one for clarinet, bassoon, and basso, and the other for two clarinets and basso. On our recording two clarinets are heard together with a cello playing the basso. The bassoon and the clarinet rarely traded places in the Classical period, and evidently here the composer had in mind the basson (a more subtle version of the French bassoon) as is stated in the title of the composition. Formally speaking, the trios comprise a set of six sonatas with an Adagio introduction, as was the widespread custom in the Classical style. Each of the sonatas has three movements, in which the introductory one is more lively (Allegro moderato) and after shorter, less formal movements there always follows a dance form of music in three-four time, with the exception of the concluding Presto. This is background chamber music that could be listened to outdoors, and it is quite possible that it was even composed for this purpose (note, for instance, the huntsman's march and the tunes of the Czech folk pastoral in the fifth sonata).

As in the sonata by Jan Zach, here, too, the sound of the unique combination of instruments is enhanced by the use of authentic period instruments.

Jiri Krejci

Jiri Krejci has for some time now devoted himself to playing an authentic period clarinet. He has performed in a number of concerts at home and abroad, and has recorded for Czech Radio and for ARTA Records. He premiered on a period clarinet in quartets by Vaclav Pichl, Jan Pavel Vesely, Jan Adam Frantisek Mica and other chamber compositions. He is often invited to seminars abroad and at present teaches at the Neruda Gymnasium and the Music School of the City of Prague.

Luigi Magistrelli teaches clarinet at the Verdi Conservatory, Milan. A clarinetist known for his diversity, he has been particularly recognized for his playing on the Müller-system clarinet. His appearances at international clarinet congresses, in the United States and China for instance, have met with success, and he has made several recordings, mostly of clarinet music from the Romantic period. On this recording of the sonatas of Zach and Vanhal he uses a nine-key boxwood clarinet by an anonymous Czech maker.

Petr Hejny is a much sought-after and widely recognized player of the cello and viola de gamba. He is a foremost Czech interpreter and an expert on period instruments. Devoted mostly to chamber music, Hejn¢ plays in various ensembles (including Pro arte antiqua Praha and the Antiquarius Consort) with whom he has made a number of well-received recordings and performed in many concerts at home and abroad, including a tour of Japan. He devotes himself also to composing and the visual arts.
