Classical Music Cd's

[puternut]

Just a general question the the length of a piece of music by a classical composer.

I see a number of multi CDs for sale where they say '100 best pieces by Bach' ( as an example).

So on 5CDs they fit 100 tracks. Given that 1cd will play for a maximum of 80 minutes so the maximum or five will be 400 minutes. 100 tracks in 400 minutes gives an average of 4 minutes a track.

Is this the full track or are they shortening them simply to fit them on? My limited knowledge is that the pieces generally run a lot longer than 4 minutes. Or am I wrong

Your sums are right (more or less - the exact size of a file depends on the content. A five minute recorder solo is about 75% of the size of five minutes of full orchestra). The record you mention is made up of short bits and many of the recordings are quite old. Here's a review which tells you the lengths of the tracks. http://www.allmusic.com/album/100-best-bach-mw0001860573

Thanks Old_Jim but my question was about these '100 Hits Of ....' in general rather than one particular release - which I truly didn't know existed.
