Each title has parts for Keyboard, Guitar, Drums, Bass, Trumpet, Tenor Sax, Trombone, and a Score.
Some charts have a Bari Sax part.
If the original recording has strings, almost all of these new charts have the string part for synth. 

The horn parts are either a three-horn adaptation of the original track, or newly composed parts.
These new original parts can be a combination of background vocals, signature guitar, bass, or keyboard licks, or new material in the style of the original track, influenced by the horn stylings of Chicago, Tower of Power, Blood Sweat & Tears,
Earth, Wind & Fire, and The Jerry Hay Horns (Michael Jackson, Seawind, Al Jarreau) among others.
The three horns parts are standardized as Trumpet, (or Flugelhorn) Tenor Sax with some Flute doubling, and Trombone.

In the scores and in the example you see in each song link,  the horn parts are in concert key for ease of analysis.
The individual horn parts are transposed to the proper key.
For guitar parts performed with a capo, the capo part is also included.​
