Key finder
Check the notes you hear: see which keys they fit, and how to choose between them by ear.
Click the notes you hear in the loop or the sample, without worrying about the octave. The site looks for the major and minor scales that contain all of them.
Possible keys
All your notes are in this scale. A minor seems more likely, because more of its tonic chord is in your notes.
One note does not fit: B.
One note does not fit: F.
Why two answers every time?
A major scale and its relative minor use exactly the same seven notes. The A minor scale is the C major scale played from its sixth note, A: the notes stay the same, only the note that sounds like home changes.
To decide by ear, listen for the note the melody lands on at the end of a phrase, and the note the bass plays on the first beat of the loop. If it is A, you are in A minor; if it is C, you are in C major. You can also compare the two “Try” buttons: the one that sounds like arriving home is the right one.
