Listen to the chord at 1:14- youtube.com/watch?v=MYzmFyN5nqo | |

| Dec 30, 2012 at 7:35 | comment | added | luser droog | I just discovered this can be made to work with a strum if you apply (palm-)muting (a little more muffling on the lower note, but mute both to keep them in tone). | |
| May 1, 2012 at 7:05 | comment | added | Ulf Åkerstedt | @luserdroog: I pluck them simultaneously using my index and middle fingers. And yes I try to have a little more emphasis on the B. (One day I might post a video, but don't get your hopes up...) | |
| Apr 26, 2012 at 16:26 | comment | added | luser droog | Do you strike them as a slap or a sweep? You want a little more intensity on the B, less on the F#, right? I can get a softer overall attack with a slap, but I can get more difference of intensity with a sweep pluck. And all with the thumb. ... | |

The perceived B, closest below the fourth interval, that I refer to, is called the cubic difference tone. See for instance 'Musical Acoustics' by Donald E. Hall, Brooks/Cole Publishing Company, Pacific Grove, CA. | |
