LilyPond users cannot efficiently reuse chord definitions with variable durations

Musicians and composers using LilyPond struggle to define a chord once and reuse it with different note durations without rewriting the entire chord structure. Current LilyPond syntax forces users to either manually rewrite chords for each duration variation or use workarounds that are unintuitive and time-consuming. This creates friction in the composition workflow, especially for complex pieces with repeated harmonic patterns.
