This is a MASSIVE display. It takes up most of my classroom’s ceiling when printed at A4.
It’s designed to help understanding of chordal relationships within keys for students from ks3 upwards. It shows all of the chords within 8 keys - those identified in ABRSM gr 1 theory - up to two sharps or one flat, both major and minor. Every poster identifies the chord on a stave and using letter names as well as stating whether the chord is major, minor, diminished or augmented. There is also a colour coding to differentiate between primary and secondary chords. Students find it very useful for composition and theory exercises as it helps them to quickly identify relationships between keys and chords.
It’s so massive, I can’t get a photograph of it but the format is as follows:
CHORD I II III IV V VI VII
There is also a colour coded explanation of how intervals work. All of the slides can be seen on the preview (all 81 of them!)
The display is presented as a PowerPoint file and a PDF. It could also work if printed A5 or if multiple slides were printed on single pages, but this would necessitate some creativity with the slide order.
