The names 3rd above relates to an ‘interval’ in singing that is commonly used to create a lovely
harmony.
The most common type of harmonisation is a third above or a third below the melody note. For
instance, if the melody of your favourite song calls for the note A over an F major chord, this
means the melody is using the third scale degree. To harmonise, you could sing a minor third
above the note A (the note C, which is the fifth of the chord) or a major third below the note A (the
note F, which is the root note of the chord). Such harmonies are pleasing to the ear in Western
music.
That’s why we chose our name, we want to harmonise with your events.
