“The Holly and the Ivy” is a traditional English Christmas carol that dates back to the 18th century. It celebrates the symbolism of holly and ivy in Christian traditions, where holly represents Jesus and his suffering (the sharp leaves symbolizing the crown of thorns, and the red berries his blood), while ivy symbolizes the Virgin Mary.
Since “The Holly and the Ivy” is a traditional Christmas carol, try to evoke a feeling of joy and reverence in your playing. Keep the rhythm steady, as it often accompanies vocals, but allow the phrasing to breathe naturally with a gentle rubato in solo arrangements.
