Leave Us Leap (J.Farley)

Originally introduced during the height of the 1940s swing era by the legendary Gene Krupa Orchestra, "Leave Us Leap" stands as an iconic high-octane instrumental showcase that defines the kinetic energy of mid-century big band jazz. Composed as a brilliant vehicle for Krupa’s powerhouse drumming and his orchestra's precision, the piece captures the thrilling, sweat-soaked atmosphere of the wartime dancehall circuits where swing reigned supreme. It remains celebrated by jazz historians and traditionalists alike as a masterclass in dynamic contrast, marrying relentless rhythmic propulsion with tightly wound, sophisticated horn writing that pushed the genre forward. John Farley’s 57-page transcription and big band arrangement meticulously recreates this historic soundscape while optimizing it for modern ensemble performance. Built around an up-tempo swing feel, the chart opens with a blistering, driving momentum. The musical character is ferocious, jubilant, and physically demanding, evoking the breathless excitement of classic 1940s bandstands. Farley preserves the essential architecture of the original recording, where the opening choruses feature lightning-fast sax lines underpinned by sharp, punchy brass interjections. Harmonic tensions remain true to the mid-century idiom, utilizing crisp block-chord voicings in the reed section and searing, high-register brass stabs that elevate the tension throughout the form. The arrangement distributes technical demands evenly across the ensemble, ensuring that every section shares the spotlight. The saxophone section carries much of the thematic weight with fleet-fingered, cascading lines, while the brass section acts as an aggressive conversational partner, demanding immaculate articulation and breath control. Improvised solo opportunities are built directly into the structure, accommodating spots for trumpet, trombone, tenor saxophone, and piano. A signature cameo appearance by the lead alto saxophone bridges the transition into a thunderous, all-hands-on-deck shout chorus. Crucially, the chart retains the famous open drum solo framework, giving the percussionist ample room to build an extended feature that can range from a few concise bars to several minutes of unbridled rhythmic exploration. Advanced high school, collegiate, and professional big bands will find this arrangement an exhilarating addition to their repertoire. Because success relies heavily on precise ensemble phrasing, light-speed swing eighth notes, and absolute mastery of dynamic shifts, it serves as an exceptional festival chart. Ensembles equipped with a technically proficient drummer and a disciplined horn section will find this piece to be an electrifying crowd-pleaser that honors the golden age of big band percussion. Conductors should establish a brisk, relentless up-tempo swing tempo from the downbeat, ensuring the rhythmic pulse remains steady without rushing. The primary technical hurdle lies in the execution of fast, synchronized swing eighth notes across the entire ensemble; light, articulated tongue-strokes are essential to prevent the fast passages from sounding muddy. Pay close attention to the dynamic markings, as the chart relies heavily on sudden drops to whisper-quiet background figures followed by explosive, full-ensemble peaks. Trumpet and trombone sections should utilize clean, bright articulation without forced tone quality in the upper registers. For the drum solo section, give the performer total freedom within the form, allowing them to quote motifs from the surrounding ensemble lines before cueing the final restatement of the shout chorus. Section leaders should run isolated rehearsals of the rapid sax soli passages at a reduced tempo before bringing them up to performance speed.
