As the immortal playwright and musician Frank Wortham once said, “If you play more than two chords, you’re just showing off.” That may be true, but even if you’re a two-chord punk snarling through a single progression, you need to know those two chords. How to proceed? Maker Brian Mercado has a solution over at hackster.io:

I have owned a guitar for a couple of years but had not spent a lot of time mastering a majority of the chords and fundamentals required for playing the instrument in a group setting. I mostly struggled with playing chords I have never played before, along with quickly switching back and forth between chords. To solve this problem, I decided I wanted to make my ENGI 301 project guitar related to address this problem. I wanted to make a device that would be able to record all guitar chords, including chords that are commonly played in many genres of music, and be able to display the tabular form of the guitar chord on an SPI screen as the program would display pictures of the tabular form at random at a set tempo. With the tabular form at display at all times, I would be able to learn my music and guitar chords quicker, and be able to challenge myself by increasing the speed of switching between chords.

See project!
