Music Theory Graphics: Scales, Keys and Modes on the Circle of Fifths #MusicMonday
Music, like math, communicates across time, culture, and language. Also like math, the invisible intricacies of music can be made clear through graphics. A lot of math make little sense to some students until it’s transformed into geometry. Likewise, the mysterious world of the circle of 5ths (and therefore key signatures) finds wonderful expression in these teaching images from Ethan Hein.
This kind of circular representation is called a scale necklace (or sometimes scale bracelet). It’s easy to transform the major scale into its parallel modes by adding and removing notes from the ends of the necklace. For example, to change the C major scale into C Lydian mode, you remove the F, the furthest counterclockwise end of the necklace, and replace it with F-sharp, adding it onto the furthest clockwise end of the necklace.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
