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
Carnatic music, the classical art form of South India, demands precise shruti (pitch) alignment, a skill novice learners often struggle to internalize within traditional oral pedagogies. This study examines the effectiveness of a culturally responsive Visual Pitch Meter (VPM) designed to enhance pitch internalization through real-time visual feedback. A quasi-experimental, mixed-methods design engaged 50 novice Carnatic vocal students (25 experimental, 25 control) across 16 sessions over 8 weeks, integrating auditory training with VPM assistance. Grounded in Constructivist learning theory, Vygotsky's Zone of Proximal Development (ZPD), and the Responsibility Alignment Framework for Learning Dynamics (RALD), the intervention reduced pitch deviation in the experimental group from 7.24 Hz to 1.14 Hz (Cohen's d = 0.54, p < 0.001). Teacher-rated accuracy and student self-efficacy also improved significantly (p < 0.001). Qualitative analysis revealed recurring themes of empowerment, initial technological adjustment, and eventual learner independence, supporting quantitative trends. Aligned with Sustainable Development Goals 4, 9, and 11, the VPM offers a scalable, culturally sensitive framework for modernizing oral music pedagogy without undermining its heritage-based learning ethos.
