For the most part, Vocal Selections are vastly simplified renditions of the numbers from a show, and very different to what would appear in a Piano/Vocal or Piano/Conductor score.
Firstly, vocal selections are designed to be accesible to a large range of performers of varying ability. Therefore, the piano writing is much simpler and will generally consist of doubling the vocal line and chords either on the beat or in the rhythm of the melody with the bassline often single notes. Notable instrumental sections of a song may be an excuse for a slightly more demanding passage. They are also generally printed with guitar chords above, which is very helpful for those who don’t read music as well, or want to perform with a guitar/small ensemble. On occasion, these chords will be incorrect, as they can be misidentified, particularly in Sondheim Vocal Selections (these should generally be avoided as they are of poor quality, and all of Sondheim’s scores are available as full piano/vocal publications.)
Vocally speaking, having the melody doubled in the piano part is often helpful to a performer who is less experienced, or just singing for fun. It can be very annoying to more experienced performers. Broadway vocal scores nowadays generally don’t double the vocal line, although it was standard practice during the golden age, as the vocal line would often be doubled on a melody instrument.
To aid both the pianist and the singer, the keys are often adjusted. This can be so that it puts the song into an easier-to-read key (Don’t Cry For Me Argentina, for example, is frequently published in C Major, whereas it appears in the show score in D Flat Major), and also so that it is an easier to sing key (a high belting song may be brought down to make it more universally accesible, especially to younger voices).
Finally, the vocal selections frequently make an attempt to divide the score much more into individual “numbers”, as opposed to what might appear in the Piano/Vocal score. This is to make it more performable and enjoyable for a solo artist. The vocal selections of Wicked are a good example of this. Defying Gravity and Thank Goodness both appear as solo songs.
The creation and publication of Vocal Selections are an art in itself, and can be the only way a score is accesible in sheet form these days, given that piano/vocal scores are now very rarely published. Many vocal selections get it wrong (too small a selection/over-simplified/convoluted arrangements), but many are spot on and are, in fact, very good substitutions for a piano/vocal score with a large majority of the score being represented. Hamilton and Half a Sixpence are recent examples of this.
Hope this goes some way to explaining the differences!
