Abstract
Composta por Radamés Gnattali (1906-1988) em 1956 para bandolim solista, conjunto de choro e orquestra de cordas, Retratos é uma suíte em quatro movimentos onde são homenageadas algumas das mais expressivas personalidades do cenário da música popular brasileira: Pixinguinha, Ernesto Nazareth, Anacleto de Medeiros e Chiquinha Gonzaga. O que dá forma e sustenta a narrativa da obra é a ideia de que os movimentos constituem retratos musicais destes compositores. Assim, a estrutura de cada movimento foi elaborada a partir de um modelo, ou seja, de cada compositor Gnattali escolheu uma peça que serviria de roteiro para o processo criativo dos retratos. Este estudo tem como foco o segundo movimento da suíte, a valsa, observando como está relacionado ao seu respectivo modelo, a valsa Expansiva de Ernesto Nazareth (1863-1934). Para ilustrar o paralelo será apresentada uma análise mais comparativa do que formal, procurando ampliar a visão do contexto histórico com evidências musicais, concentrando-se principalmente nos elementos comuns a ambas as peças.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
