Each corner is a ten-point rating. The further out, the higher.

The difference, by ear

Space rock takes the same stasis toward electronics and repetition rather than toward blues improvisation.

Both are sung cleanly and move at much the same pace, around 90 to 140 bpm. To hear the difference, play Blue Cheer next to Hawkwind. Both grew out of psychedelic rock, acid rock first and space rock two years after.

Put together from each genre's vocals, tempo, song length, key acts and place in the tree.
