What is Reddit's opinion of Circle of Fifths?

From 3.5 billion Reddit comments

1. Download any Circle of Fifths app and type in the key of the song. I usually noodle on the 6th string to find the key. Once you hit generate or whatever, you will most likely find all applicable chords highlighted.
2. Play with the indicated chords and see if they are on the song. Figure out the order of the chords in the progression.
3. Play with different variations of the same chords to see if you need it to be open, chimier, higher in the fret, etc.
4. If you are looking for triads, find the chord first, and then figure out which note is the 1st, 3rd, and 5th respectively. Then, look at a fretboard map and find those notes. Play any combination until you find one with either the right tone or the right place in the fretboard, in relation to the other chords/triads/arpeggios.
5. If you are looking for arpeggios or solos, we are talking scales and modes.

1. Hot cues. No harm in setting through the track at points of change or interest.

2. Try the Beatport Pro program for MAC/PC. It has a function to sync you tracks to the Beatport library and update your metadata.

3. Try this app if you are using an Android phone. https://play.google.com/store/apps/details?id=com.gmail.wesoftlab.circleoffifths
