For those classical singers instead who would like to improve their knowledge of a specifica aria, it is possible to download two other useful learning tools; a "Vocal Line Track" and a "Diction Track", both found in the "Professional Pack" (please note the Professional Pack also consists of the Karaoke Pack, in other words, includes the piano accompaniment and the cdg file).
The "Vocal line track" is an audio file containing only the vocal line; it is possible to overlap the "Vocal Line Track" to the accompaniment track with the use of an audio editing program. The "Vocal Line Track" is extremely useful for improving the intonation and rhythm of vocal parts (follow our learning method).
The "Diction Track" is an audio track containing only the spoken part of the line; listening carefully to this, those not familiar with the toungue in which the aria is written, can eliminate pronounciation defects.
As above, with the use of an audio editing program, you can listen to this track overlapping it to the accompaniment and "Vocal Line Track".
