Chamber music for three, four, and five instruments comprised Sunday night's concert by the Adams House Musical Society. All three selections are familiar fare to most concert-goers, and the performances on the whole did full justice to the music.

Mozart's tuneful Clarinet Quintet opened the program. In his divertimenti, symphonies, and particularly in this quintet, one is well aware of Mozart's skill in exploiting the distinctive tone of the woodwinds. The clarinet's warm timbre is well suited to this warm music. Clarinetist Aaron Johnson, '49, turned in a fine performance. His intonation was consistently good, and he was not at all bothered by the many big skips, including the double octaves. The rest of the ensemble, violinists Barbara Sorenson and Earl Ravenal, violist Vernon Head, and cellist Joan Brockway provided an unobtrusive accompaniment. Their tone, although a little thin, improved as the piece progressed.

The Trio in E flat, for the weird combination of piano, violin, and French horn, is one of the most delightful of Brahms' early creations. The three instruments sound surprisingly well together and the music itself, though-not possessing the vitality and depth of the more mature composer, has many interesting moments.

Jaroslav Hulka, '52 coped valiantly with the difficult horn part, but cracked several notes and missed a few altogether. Nevertheless, Mr. Hulka had a good, strong tone and when he hit a note he hit it solidly. Outstanding for her sensitive interpretation of the piano part was Mrs. Norma Sapp, whose talented piano-playing husband, Allen Sapp, was relegated to the roll of page-turner.

One of the acknowledged masterpieces of chamber music, Beethoven's opus 95, was the group's final offering. A product of Beethoven's middle period, this powerful quartet was the best part of the program, and was the best playing. The four performers captured the fierce intensity of this music and although they could not always project the inner conflict of the work, they acquitted themselves admirably. The final allegretto agitate, full of stringent rhythms and harmonies, brought the evening to an exciting close.
