Watch the Diminished Fifth online guitar lesson by Kai Eckhardt from Atomic Bass: Reactive Intervals

There is a nice symmetrical quality to this variation of the tri-tone, but the big uncomfortable slide is still part of the equation. On five or six string bass you can avoid it, but I want to make sure every player including the 4 string bassists can dive into these sounds. Jaco would not have complained about it - there you go! One word of caution. When sliding across one string with one finger be careful not to give yourself burn marks. As an alternative you can jump to the higher note or touch the string lightly.
