The song 'Killer Queen' by Queen starts with a piano and includes distinctive vocal leaps in the melody, especially in the chorus.
Step-by-step explanation:
The question seems to be referring to the song Killer Queen by the band Queen. The song mostly starts with a piano playing a descending chromatic line. This is quickly followed by the introduction of a guitar and drums.
The song features several small vocal leaps that are considered distinctive, especially in the sections where Freddie Mercury sings phrases like “she's a Killer Queen” and “Dynamite with a laser beam.” These leaps give the melody a unique and catchy character.
