Concerto for Piano No. 4 in G minor, Op. 40 (First revised edition, 1928): Full Orchestra, Solo Keyboard with Ensemble, Conductor Score & Parts (EDWIN F KALMUS)

This score captures a fascinating moment in Rachmaninoff's creative life—a work substantial and deeply felt, yet one that the composer himself deemed incomplete. The 1928 revision strikes a balance between the original's ambitions and practical performance considerations, offering conductors a chance to lead an underperformed masterwork that deserves more concert time. Programming this version shows musicians a different path through Rachmaninoff's piano concerto canon.

The concerto unfolds with a restless, searching quality that sets it apart from Rachmaninoff's more extroverted keyboard writing. Lyricism emerges and dissolves, overtaken by darker harmonic turns and moments of genuine orchestral grandeur, creating a work that feels both intimate and monumental, never settling comfortably into either register.

This Kalmus score serves professional orchestras and advanced music schools seeking an authoritative, practical edition of a rarely heard Rachmaninoff concerto, alongside pianists with substantial technique and musical maturity. Conductors building a season around lesser-known twentieth-century repertoire will find this 1928 version a compelling alternative to the more familiar 1941 revision, offering a direct window into the composer's initial vision for the work.

• Balance the solo piano's lyrical passages against full orchestral textures by respecting Rachmaninoff's dynamic markings precisely; the orchestra must recede during the soloist's introspective moments without sounding thin or disconnected.
• Establish a clear pulse with the brass and timpani sections before the concerto's first rehearsal with soloist, as the work's harmonic density can blur rhythmic clarity if the foundation isn't rock-solid.
• Allow the piano and strings to phrase with freedom during the slower sections, but maintain ensemble cohesion by having winds and brass mark clear subdivision points where the soloist must align with the orchestra's framework.
• Conduct the cadenza passages with a light touch; indicate the soloist's entries clearly without imposing a strict metronomic grid that will undermine the performance's spontaneity.

Consider this concerto as the centerpiece of a program exploring Rachmaninoff's evolving approach to the form across his lifetime, or as a bridge between Romantic virtuosity and early twentieth-century modernism in a thematic season. Its relative rarity makes it an exceptional choice for a composer-focused concert, where audiences and musicians alike can discover a significant work outside the standard canon.

• Ensemble coordination between a virtuosic solo part and complex orchestral writing
• Conducting through rapid harmonic shifts and key ambiguity typical of early twentieth-century Russian modernism
• Balancing lyrical solo passages against full orchestral accompaniment without loss of textural clarity
• Reading a full conductor score with doubling across multiple instrumental families
• Rehearsal techniques for synchronizing a technically demanding solo keyboard part with orchestra across extended structures
