Hi students.
In this report I am going to speak in general about ska.
Ska is a music genre that originated in Jamaica in the late 1950s.Ska combines elements of Caribbean mento and calypso. In the early 1960s, ska was the dominant music genre of Jamaica and was popular with British moods. Later it became popular with many skinheads
Ska combines drums, saxophone, trombone, trumpet, electric guitar, bass and singer.
Drum: A drum set is a collection of drums, cymbals and sometimes other percussion instruments.
Saxophone:  The Saxophone is   considered a member of the woodwind family. Saxophones are usually made of   brass and are played with a single-redd mouthpiece similar to that of the clarinet.
Trombone: The trombone is a musical instrument of brass family. Like all brass instruments, sound is produced when the player’s vibrating lips.
Trumpet: The trumpet is a musical instrument with the highest register in the brass family. Trumpets are among the oldest musical instrument, dating back to at least 1500 BC.  
Bass:  The electric bass guitar also called electric bass, or simply bass. Is a stringer instrument played primarily with the fingers or by using a plectrum.
Electric guitar: An electric guitar is a guitar that uses pickups   to convert the vibration into an electrical current, which is made louder with an instrument amplifier.  
And to finish with the reporter I’m going to put a ska song.
PERSONAL EXPERIENCE AND OPINION:
I like very mach the ska music and I stay in a lot of ska concerts. Apart of this I can say that I play the trumpet and also know a bit of saxophone.
In my opinion ska is the vest music style because I motivate a lot and is very easy to dance.
