A music key is a system of functionally related chords and notes that form the harmonic foundation of a piece of music. Each key is characterized by a tonic, which is a central or resting note, and a unique combination of intervals between the tones. Major keys have a happy, upbeat sound created by emphasizing the major chords of the key. Minor keys often sound sad and sorrowful, and they prefer to dwell on darker-sounding minor chords.

How to Figure Out the Key of a song by ear

Begin your musical exploration by engaging in attentive listening. Identify the note or chord that feels like the central point, often referred to as "home" or "Doh" in solfa notation. This note, also known as the tonic or root, serves as the resolution for the entire composition.

Once you've found your "Doh," whether a note or chord, proceed to sing the major or minor scale, using this as your starting point. Cultivating a discerning ear requires time and consistent practice, so remain patient and persistent as you develop this valuable skill.

How to Determine the Key of a Song by Key Signature

Every musical key is associated with a distinct collection of sharps or flats. The key signature is usually found at the beginning of a piece of sheet music, right after the clef. (For sharps, the order is F#, C#, G#, D#, A#, E#, and B#. For flats, the order is B♭, E♭, A♭, D♭, G♭, C♭, and F♭. )

To determine the major key for sharps, the key is the note that is a half step above the last sharp in the key signature. For flats, the key is the second-to-last flat in the key signature. To find the relative minor key, for both sharps and flats, the relative minor key is found by going down a minor third. Finally, you should listen to the music to confirm the key.
