Creating "Melody and Chord Arrangements", in theory are as simple as harmonizing the melody with a chord. Which is playing a chord that has the melody note as the top note of the chord voicing. In practice it is a little more involved, but not much more.

Yesterday is a song originally recorded by The Beatles for their 1965 album Help!. The song first hit the United Kingdom top 10 three months after the release of Help!. The song remains popular today with more than 1,600 cover versions, one of the most covered songs in the history of recorded music. The song was not released as a single in the UK at the time of its release in the United States, and thus never gained number 1 single status in that country. However, “Yesterday” was voted the best song of the 20th century in a 1999 BBC Radio 2 poll of music experts and listeners.
