What you can check on the guitar

This reading uses Dm, Gm, A7 and Dm, the progression CifraLab proposes for a “Mystery & Dramatic Tango” feel. What follows can be checked by playing.

From Dm to Gm, D stays, and one hand position stays put. Gm and A7 share G, though the hand changes shape. From A7 to Dm, A stays, but no fretted position repeats. Going back from A7 to Dm, C# rises a semitone to D and G falls a whole tone to F. The two chords share D, F and A.

“Mystery & Dramatic Tango” runs at 100 beats per minute, so each beat lasts 600 milliseconds. If each chord takes one bar of four beats, the full cycle lasts 9.6 seconds. Read in D minor, its degrees are i, iv, V7 and i. In Dm you hear D, F and A. Gm holds G, Bb and D. In A7 you hear A, C#, E and G.
