When playing instruments, being in tune is often a key component to whats deemed a "professional" recording - but David bennet is here to explain how it's almost impossible with guitars, synths and pianos. In the video he explains 12 tone equal temperament, which is used to tune most fretted and fixed instruments and how it's technically out of tune - or not justly tuned as we might perceive.
Fretless instruments like violins, cellos, and double basses are able to stay in tune as demonstrated by the violin demonstration in the video. Interesting point, more videos on musical theory, scales and tuning on Davids channel below.
