Verified content

• [full text] Meta-analysis of 13 studies (N = 788) linking task-specific accumulated practice (including deliberate practice) to objectively measured musical achievement.
• [full text] Mean corrected correlation rc = 0.61 (95% CI [0.54, 0.67]); mean true-score ρ = 0.61; observed mean ro = 0.54; homogeneous after correction (I² = 0%).
• [full text] Authors warn against reading rc = 0.61 as “explains 36% of variance”; they treat it as the association under their psychometric framing and as a lower bound on the true DP effect.
• [full text] Higher than Hambrick et al. 2014 music estimate (rc = 0.52 in their comparison).

Project use

• [assessment] Applied 2026-10-27 extra6 as C16 kill-condition survival: under C16’s majority-of-variance kill (>50%), even r = 0.61 (r² ≈ 37%; upper CI r = 0.67 → r² ≈ 45%) stays below half in the music domain.
