VCD karaoke machines allow one to sing along to a preferred tune as the words move across the screen. Besides they have been designed with features that adjust the music pitch electronically. This makes it easier for anyone to sing any music type as one will just choose the key that best suits his/her vocal range. VCD karaoke machines also have a dual microphone input which allows two people to sing at the same time making the experience even more enjoyable. Quite a number of VCD karaoke machines display up to about eight languages which also enable one to sing along to tunes that are not written in English.
