Each selected Undertale score names an arranger alongside the music credit to Toby Fox: ThoseTwoLetters for the tenor trombone version, and Bigyihsuan and Stoh for the piano versions. These are arrangements, and the available information does not establish that any of them is the original game score. Check the score itself for the fullest credit information.
Two separate piano arrangements are available: “Undertale - Undertale (Piano Arrange)” credited to Bigyihsuan, with an opening tempo of 106 BPM, and “Undertale: Undertale (Piano)” credited to Stoh, with an opening tempo of 100 BPM. Both show 4/4 and three flats at the opening. These tempo figures describe the openings only and do not establish difficulty.
“Undertale Themes for Trombone” is the selected score that specifies tenor trombone. It shows a 4/4 opening in three flats at 230 BPM. The plural word “Themes” suggests more than one theme, but the available score information does not identify the individual pieces, so confirm the contents before choosing it.
Instrumentation, opening time signature, opening key signature and opening tempo are useful starting points for comparing these Undertale arrangements. The available information does not establish a difficulty grade, a verified edition, complete contents, original instrumentation, or that a version can be played on another instrument. Check the actual score before making a choice.

The music in the selected Undertale arrangements is credited to Toby Fox, with separate arrangement credits for ThoseTwoLetters on the tenor trombone version and Bigyihsuan and Stoh on the piano versions. Those credits identify the people named on the scores; they do not by themselves verify the history of the original game soundtrack.
Two of the selected Undertale arrangements are for piano, and one is for tenor trombone. The piano scores are titled “Undertale - Undertale (Piano Arrange)” and “Undertale: Undertale (Piano)”; the trombone score is titled “Undertale Themes for Trombone.”
The two piano arrangements are separate versions by different arrangers. “Undertale - Undertale (Piano Arrange)” is credited to Bigyihsuan and shows an opening tempo of 106 BPM, while “Undertale: Undertale (Piano)” is credited to Stoh and shows an opening tempo of 100 BPM. Both show 4/4 and three flats at the opening, and the tempo figures describe only the opening.
All three selected Undertale scores show an opening time signature of 4/4 and an opening key signature of three flats. Their opening tempos differ: 106 BPM and 100 BPM for the two piano versions, and 230 BPM for the tenor trombone version. These details describe the openings only and do not establish a key name or difficulty.
“Undertale Themes for Trombone” is listed for tenor trombone and shows a 4/4 opening in three flats at 230 BPM. Its plural title suggests more than one theme, but the available score information does not identify the individual themes, so its exact contents need to be checked in the score.
These Undertale scores are arrangements: each one names an arranger alongside the music credit to Toby Fox. The available information does not establish that any of them is the original game score or that they reproduce the original instrumentation.
