Holmboe's last quartet work which is unoffi­cially also String Quartet No. 21 was the last work he ever composed and was unfinished on his death in 1996. His pupil Per Nørgård has finished the quartet and himself characterizes his contribution by saying that the score existed “in an only partly completed form which could however be written out with only a few cases of doubt”. With only two movements and a play­ing time of about nine minutes it is at its exist­ing length the shortest of Holmboe's string quar­tets. The first movement takes the form of one long arch in a rocking triple time which constantly shiftsamong different tempo and pulse sensations. At the same time the rhythmic en­ergy increases until the movement in a faster Con moto tempo accelerates to a more flowing 12/8 time coloured both rhythmically by cross-­rhythms in duple time and timbrally by harmon­ics in the viola. In its middle section Con fuoco the movement culminates in both tempo and expression until it falls calm in brief recapitula­tions in reverse order of the first two sections. The rocking feeling continues in the second movement but now at a more extroverted level from the outset Allegro and pizzicato. The en­ergy builds up further as the mood intensifies to Con fuoco while all instruments go over to bowed playing but like the first movement this movement ends Adagio here however not as a gradual attenuation but through a sudden shift in tempo to a calm imitative passage before the movement slowly thins out to the almost inaudible through a last dense open sounding chord with a brief violin solo above it. The quartet is dedicated to Holmboe's wife MeLa May Holmboe and was given its first performance by the Kontra Quartet on 22nd March 1997 at the Carl Nielsen Academy of Music in Odense Denmark.

To see the summer sky for Violin and Viola falls into four movements. The first movement opens with the two instruments sounding almost as one playing very high glassy harmonics. Gradually an expressive viola solo emerges withboth instruments descending to their lower ranges. A livelier quasi scherzando solo for violin accompanied by viola pedal notes leads to a chorale like passage the violin at the top of its range whilst the viola is at itslowest. The movement ends with the two instruments coming together once again on a unison Bb and fades away almost as it has begun but this time in the husky lower registers.The second movement is much faster and openswith a downward flurry for both instruments. A continuous pizzicato line for viola is interrupted by more violent passages in the violin. The two instruments come together in a dance-like passage before the roles are reversed.Finally an ecstatic melody surfaces in the viola and is later continued in the violin before the movement closes with the spiky figures of its opening the two instruments ending in unison.The third movement encompasses isthe most delicate and still music of the piece. After a very tranquil opening an expressive violin melody is accompanied by a gentle rocking figure in the viola. Tentative at first intensity and speed gather until the violinreaches stratospheric heights. Both of the instruments play at the extremes of their registers before moving to common ground for a more lively textural passage. This is followed by a passionate reminder of the movement’s opening gradually fading away to nothing.The piece ends with a Moto Perpetuo. The instruments begin by dovetailing a single line which develops into two strands before a more violent section appears punctuated by strident doublestops. Both instruments have slightly manic solo episodes before the movement quickly dies away in the single line of its opening

Work for Oboe Violin Viola and Cello. Parts available: CH56341.This quartet was commissioned by the Institute of Contemporary Arts and written in the autumn of 1967. It is dedicated to Lady Norton and is the second of LennoxBerkeley’s three works written with the oboist the late Janet Craxton in mind the other two being his Sonatina OP 61 and Sinfonia Concertante OP 84.The work begins with a fairly extended introduction leading without a breakinto an Allegro. The whole composition is based on the internal of a third (sometime major sometimes minor) which is heard in the opening phrase of the introduction and again in the main theme of the Allegro though here in atotally different context. The allegro is in more or less traditional sonata form. The middle movement is a kind of Scherzo growing out of a rhythmical figure for the strings and a rapid arpeggio (major and minor chords) forthe oboe. This is a Presto; a more relaxed middle section corresponding to the Trio in a classical work is followed by a much shortened version of the Scherzo. The last movement is brief but very slow all four instrumentstaking up in turn a gently rocking figure that moves to and fro between two notes always a major or minor third apart. The music becomes more animated but returns to the opening figure and dies away each instrument droppingout one after the other leaving the cello alone in the last bar.
