Figuring Out the Relative Major of Any Minor Key
When you are looking for the relative major of E minor, the answer is G major. The method to get there is straightforward: count up three semitones from the minor tonic, or think of it as the third scale degree of the minor key becoming the first degree of the major key. Here is what that looks like in practice. E minor shares the exact same key signature as G major — no sharps, no flats. The notes in both keys are E FG A B C D and G A B C D E F#. They use identical material; you just center your tonal gravity around different roots. That is why they are called relative keys. The quickest way to find it without doing interval math is to look at the natural minor scale and pick the note that sits on the third degree. In E natural minor, that is G. Put G as the new root, play the same seven notes, and you have G major. Reverse that process for any other key: find the third degree of the minor scale, that is your relative major.
I run into this when I am transposing songs for guitar players who refuse to use flat key signatures. A piece in E minor looks brutal on paper with all those F#s and Bif you force it into a major framework, but it is clean as a whistle in G major. I usually just hand them the G major chart and tell them the chord progression maps directly. The vi chord in G major becomes i in E minor. That single relationship explains most of the harmonic overlap. There is a common pitfall people hit when they confuse relative major with parallel major. The parallel major of E minor is E major, which has four sharps. Totally different key signature, totally different sound. Relative and parallel are not the same thing. I see this mistake all the time in beginner theory forums. Just keep in mind: relative means share the key signature, parallel means share the same root note. Another thing that trips people up is the harmonic and melodic minor variants. When you raise the seventh degree in E harmonic minor, you get a Dleading tone. That Ddoes not exist in G major, so suddenly your relative major relationship gets muddy if you are trying to borrow chords from the harmonic form. The pure relative major only matches the natural minor. Once you introduce accidentals from harmonic or melodic minor, you are borrowing from outside the parent major key, which is standard practice but worth being explicit about.
I once transposed a jazz standard from D minor into its relative major, F major, and got confused because the tune was using lots of harmonic minor passings. The borrowed chords kept pulling back toward D minor even though we were notating everything in F major. My workaround was to notate the tune in F major but mark the harmonic minor accidentals explicitly instead of trying to rekey the whole thing. It saved me from rewriting charts that were already legible in the original key. Here is a quick mapping of some common minor keys to their relative majors: A minor to C major

B minor to D major You can also work backwards from a major key to find its relative minor. Drop down three semitones from the major tonic. From G major, go down G to Fto F to E, and you land on E minor. This direction is useful when you are analyzing pop songs that seem to sit in a major key but have verses that feel minor. Check if the verse is playing around the vi chord, which is the relative minor. One practical use case is when you are trying to match vocal ranges. If a singer is comfortable in G major but the original track is in E minor, you can just shift the melody and chords up three semitones and everything aligns. The harmony stays functionally identical because you are just relabeling the same pitch classes. This usually takes me about ten seconds to work out, compared to fifteen minutes of trying to force a transposition that does not fit the voice.
Do not overcomplicate this. The relative major of E minor is G major. Share the key signature, use the same seven notes, center the tonality on G instead of E, and you are done.
