Hi Guys, This is a pretty general question. I'm aiming for RockSchool Bass Grade 4 in June this year and I recently started tackling the course material. The first two tracks place strong emphasis on the ability to improvise (which is a weak spot for me). Grade 3 was not so bad because all solos were tied to a particular key; I simply chose a pentatonic scale and tried to make it sound musical. Grade 4 has me soloing over chords which I cannot tie to a particular key (and that's fair; it's Grade 4 so I should be able to solo fluidly through any given chord progression). The last few bars are as follows ... |: A7sus4 | A7 | Dm7 | Dm6 :| [*4] I've been reading Chris Chaney's recent BassPlayer Column about assigning scales to Triads (or 7th chords) so I did the following ... For the first chord, the chord tones are A D E G. From what I understand, a scale like ... A C# D D# E F G A ... could be used to create a solo. For the Dm7 chord, the chord tones are D F A C. A scale like ... D E F Ab A B C ... could be used to create a solo. (incidentally, what are the 4 chord tones of Dm6?? Are there 4 tones or only 3) Please correct me if I'm wrong with the above scale assignments. Is this the theoretical approach most of you would take for a solo over the above chord progression? Are there simpler ways to assign a scale to a solo? For example, is there a single pentatonic scale that would suit this chord progression or is Vertical Soloing the only way through this mess. The solo on Grade 4 Track 2 is particularly challanging so I need to get the correct approach here. I'd appreciate any help anyone can offer (weblink or whatever). All the best, Rob.
