Hierarchical neural integration of musical structure during expert performance.
Article in bioRxiv : the preprint server for biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Music, which is organized hierarchically (notes, phrases, sections), provides an ideal model for studying fine-grained motor sequence production. However, it is unknown how musicians' brains integrate tonal structure over multiple timescales during real-life performance. Here, we scrambled an unfamiliar Tchaikovsky piano suite at four timescales-every 1/2/8 measures, or fully intact-and asked expert pianists to play (sightread) all four versions in the fMRI scanner. Responses in the motor network, default mode network, and hippocampus were strongly impacted by scrambling, indicating that they integrate tonal structure over relatively long timescales. Additionally, the emergence of functionally connected sub-networks between auditory, visual, motor, and default mode network regions across scramble levels supported this hierarchical integration process. Our results cannot be explained by lower-level cues (tempo, timbre, dynamics; local pitch height or rhythmic density) and instead reflect processing of high-level tonal structure. Our study highlights novel mechanisms of complex auditory-motor action planning during live music performance.
