The instruments
Grouped the way an orchestra is: by how the sound is made. Each one has a breakdown of what it is doing physically, drills worth the time, the practical tips nobody writes down β and the songs in the library that suit it.
Keyboard 2
One key per pitch, the whole harmony under two hands β the fastest way to see theory.
Strings 11
Pitch set by string length: stopped by a finger, sounded by a bow, a pick or a nail.
Woodwinds 11
A vibrating column of air, shortened and lengthened by opening holes along the tube.
Brass 8
Buzzed lips drive the column; valves or a slide add length to reach between harmonics.
Percussion 13
Struck, shaken or scraped β some pitched, most of them carrying the time instead.
The roster and the βheard onβ links come from π» MUSIC INSTRUMENTS [DB] in Notion. The breakdowns, drills and tips are written into the site. Practice suggestions are derived from the pipeline's measured key, meter and chord data β nothing here claims to know who played on a record.
