Picked one by one from a mixed channel. Transcript check: both title readers certain; 4 of 5 sampled certain picks confirmed by transcript, none failed. Channel rule: Include only the standalone piano tutorials that teach a specific concept with a descriptive, non-hype title (voicings, progressions, scales, ear training, comping, or a style breakdown such as stride, Garner or McCoy Tyner); exclude podcast/interview episodes, teaser clips, performances, mindset/motivation videos, generic tips lists and any title using all-caps hype or withheld-information hooks.
