I have this notes I extracted from a song using Adobe Audition’s frequency analysis.
D F# A C# (Dmaj7)
E G B D (Em7)
F# A C# E (F#m7)
G B D F# (Gmaj7)
A C# E G (A7)
B D F# A (Bm7)
C# E G B (C#m7b5)
In parenthesis is the corresponding chord found by a chord finder. I presume Dmaj7 could be the tonality but I'm not sure, does anyone know what could it be?
