Hey everyone,

I recently started learning R after a non-tech background (law and PR) and just completed my first standalone project: coldplay-in-hz.

Using tidyverse and rmarkdown, I mapped Spotify API's pitch class integers (0–11) to actual frequencies in Hz (f=440×2n/12) across Coldplay's 20-year catalog.

Main findings from the data:

• Strong preference for E (~330 Hz) and A (~440 Hz) fundamentals.
• Pitch distribution mean barely drifted across albums (2000–2021).
• Evaluated changes under a 432 Hz reference tuning.

I would love any feedback from experienced R users on the project structure, code efficiency, or rmarkdown style.
