Final answer:
The dominance of electronic sound is not a characteristic of guitar band highlife; instead, the genre is known for fusion of African and Western musical elements, use of traditional instruments, and danceable rhythms.
Step-by-step explanation:
The characteristics of guitar band highlife incorporate a rich blend of distinctive features. Two of those features include fusing African and Western musical elements and delivering danceable rhythms, both integral to the genre's appeal. Typically, highlife music may include a range of traditional instruments which contribute to its unique sound.
In contrast, the dominance of electronic sound is not considered a characteristic feature of guitar band highlife, as the genre tends to maintain a more acoustic and organic sound profile that relies on the traditional instruments rather than heavily processed electronic sounds.
