| 摘要 |
The invention provides an apparatus which comprises a recording of a musical composition having two or more parts. One of the two or more parts is at a volume audibly louder than an audible volume of the other parts when the recording of the musical composition is reproduced. This part at a louder volume is the part to be learned efficiently and accurately. The musical composition may comprise instrumental and vocal parts in any combination, and the part to be learned (and therefore at a louder volume) can be an instrumental or vocal part. Methods of making the apparatus and methods of using the apparatus are also provided.
