Circle of Fifths Mug Koffiemok

This mug features a classic Circle of Fifths diagram wrapped around a light blue ceramic body, showing all 12 major keys with their signatures in black notation on white segments. Key symbols like C (no sharps/flats), G (one sharp), and F (one flat) form the clockwise wheel, with staff previews for easy reading—perfect for quick reference during coffee breaks.​ Beginner Benefits: New musicians get instant key lookups without charts; spot two sharps for D major while sipping. Ideal for ukulele or concertina players learning progressions like I-IV-V (C-F-G). Durable white handle contrasts the blue design for a clean, motivational practice tool.​​
