Therefore， some cheerful melody or chord ， such as 15，351，535 ， of which five tone is repeated so frequently ， and the effect may be just 153，153 ， so pay attention to the chord adaptation ;Melody is also true， if adaptation is not good， the taste of losing the original song You should consider the : is it not suitable to get a paper tape .
