Chaconne. Par LERDAHL FRED. Chaconne (2016), for string quartet, was commissioned by the Daedalus Quartet to celebrate its 15th anniversary. The commission was supported by New Music USA, made possible by annual program support and/or endowment gifts from Pennsylvania Council on the Arts, Helen F. Whitaker Fund, and Aaron Copland Fund for Music. My music has a substantial history with Daedalus. I composed the Third String Quartet (2008) for them, and subsequently they performed my three string quartets on several occasions and recorded them brilliantly on Bridge Records (Bridge 9352: Music of Fred Lerdahl, vol. 3). Chaconne is in one movement lasting 19 minutes. It is effectively my fourth string quartet. Quartets 1-3 form a unified cycle lasting 70 minutes. When I finished the cycle, I thought I would never write again for the medium; yet I could not resist the opportunity of working again with Daedalus. The issue was how to compose another string quartet unrelated to the earlier cycle. The solution came from my solo cello piece There and Back Again (2010), which was based on a four-bar variation pattern from a 17th-century chaconne. Unlike the asymmetrical phrases and expanding variations of much of my music, the chaconne form requires symmetrical phrases and strictly periodic variations. I wished to work again with these symmetries but on a larger scale. Chaconne also differs in character and expression from the three-quartet cycle. The cycle is inward and intense, a kind of psychological excavation. Chaconne is, for the most part, transparent and playful. Many of its textures emerge from little canons, not completely unlike the rounds that children sing. Any composer who writes in chaconne form (one thinks above all of the last movement of Bach’s D minor violin partita and the finale of Brahms’s Fourth Symphony) is confronted with the challenge of how to create a larger form out of a constantly repeating pattern. My Chaconne grows from paired antecedent-consequent phrases, each variation lasting eight bars. The 50 variations group into three large rotations, forming three arcs of tension and relaxation, with subtle parallel connections across the rotations. Notwithstanding my attraction to chaconne form, I purposefully disguised its symmetries and periodicities in order to build an overall dramatic shape. Fred Lerdahl/ Répertoire / Quatuor à Cordes

Commissioned by the Presteigne Festival of Music and the Arts Limited with funds provided by the Arts Council of Wales for premiere in August 2012 by the Carducci String Quartet in St. Andrew?s Church Presteigne.Composer's Note'Some years ago I noted down the opening theme of what I anticipated would be a relatively Classical string quartet ?Classical? in the sense of the forms adopted plus perhaps a predominantly lyrical tone of voice. The commission for this work from the Presteigne Festival for their 30th anniversary in 2012 gave me the opportunity of putting into practice this long-held idea. It isdedicated to the Festival and to the Carducci Quartet whose career as much-admired friends and colleagues I have greatly enjoyed.The only break with ?classical? tradition is that there are five movements instead of four with two Scherzi as the second and third though both these are very short and contrasting. I found myself listening to Haydn?s string quartets a lot before and during the composition of this work and I hope the spirit of his delight in writing for this medium is echoed in my own music. The opening movement is in sonata form unusually for me and lyricism is I hope the basis of it though there is a good deal of activity at times. The Scherzo light and marked by frequently-changing rhythms is followed by an equally short but ferocious Perpetuum mobile marked Wild und rasch (one of my favourite German tempo markings). The fourth movement is an intense Adagio in which a single phrase uttered strongly in unison is gradually transformed into gentle diatonic chords before the close intermingled with cadenzas for cello for viola and for the two violins together. The finale (a Rondo) resumes the classical tone of the first movement but apart from one dance-like episode it builds up a fair head of steam towards a final Presto which however ascends slows and quietens towards a gentle summer sky at dusk.'
