| Hey,
I been playing with sweeps for a bit now, I wrote a lesson on activebass if that's any help i'll pm the link to you.
Here's a couple of my patterns which may be of use:
This one will perfect your 2-octave minor sweeps, it pedals on a high A whilst moving Am, Bm, Cm, Bm
G --------5-9-14-9-5-----------------7-11-14-11-7---------
D ------7-------------7------------8----------------8------
A ----7-----------------7--------8--------------------8----
E 5-8---------------------8-7-10------------------------10-
G -----------8-12-14-12-8-----------
D --------10---------------10--------
A -----10----------------------10----
E 8-11----------------------------11-
G --------7-11-14-11-7----------
D -----8----------------8--------
A -----8--------------------8----
E 7-10------------------------10-
Here's another, this time based on a three stringed one octave sweep, chords are G#maj7 Gmin (inverted) and Cmin
G ------8-12-8----------8-12-8-----------12-15-12-----
D ---10--------10----10--------10-----12-----------12-
A 11--------------11---------------13------------------
E ------------------------------------------------------
G ------12-15-12------------12-17-12-----------12-17-12----
D ---12-----------12-----13-----------13----13-----------13-
A 13------------------15-----------------15------------------
E ------------------------------------------------------------
If you need any help with these lemme know, but if you just want some arpeggio based patterns then here ya go. Have fun. |
