Why do some minor keys sound like major keys, and vice versa?

[Breakthrough Guitar]

For every Major key, there is a Minor key that shares the exact same notes. This is called a "relative Minor key". The reason these two keys can sound the same is because you are literally playing the exact same notes.

What makes the difference in the overall sound, is what the background music is playing. If the "home" chord in the background music matches the "root" note in the Major key, your scale will sound major. If the "home" chord in the background music matches the "root" note of the Minor key, your scale will sound minor.
