Coast was established, European missionaries and merchants brought with them accordions, brass instruments, guitars and harmonicas. The sounds of these instruments combined with the more traditional drum-focused music of West Africa to create the fusion that is highlife. A major factor in highlife's increase in popularity during the mid-20th century was the desire to raise spirits after World War Two. Calypso music remains popular throughout West Africa. Developed from West African kaiso, the sounds of calypso are similar to those of highlife, however the two differ slightly in lyrics and instrumentation. Lyrics in highlife are generally repeated more than those in calypso songs, despite the two genres' subject matter remaining similar - both are commonly about romantic relationships and desire.

Afrobeat is a music genre with major popularity throughout West Africa. Originating in Ghana in the early 20th century, Afrobeat grew in popularity in the 1960s. This growth was mainly due to the considerable fame of Fela Kuti, the ‘Father of Afrobeat’, and other pivotal artists such as Tony Allen and Ebo Taylor. Afrobeat is influenced by palm-wine music and Ghanaian highlife, as well as jazz, funk and fuji. Fela Kuti devised the term 'Afrobeat' as early as 1968 in his home country of Nigeria. Afrobeat music is characterised by multi-instrumental bands playing a jazz and funk-inspired groove with a focus on guitar riffs and horn sections. The lyrics have historically been political in nature, with Fela Kuti’s lyrics covering topics from black power to dictatorship. The earlier sounds of Afrobeat have influenced Western artists such as British producer Brian Eno and American rapper Talib Kweli, while American EDM group Major Lazer are known for the regular inclusion of rhythms inspired by Afrobeat in their music. Afrobeat is commonly confused with Afrobeats, the latter being a more general term used to describe popular contemporary music throughout West Africa. A distinct trait of Afrobeats’ sound is its focus on drum rhythms, commonly made electronically. Davido, Wizkid, Burna Boy Tekno are highly popular West African Afrobeats artists.
