Bob C. I see why you'd say that but if you're talking about Ex 24, it's not really a harmonic progression. It's just 4 unrelated chords so I took it to mean that the intervals should be the same.

Bob C. No it's not repeating the same notes its repeating the same shape but the notes need to conform to the chord

Melissa C. Nope. Do tell

That's cheating. I was gonna give you a response. BTW look at the melody in measures 9-12, it's the Chipmunk Song "we can hardly stand to wait..."

Eric, that's great! Love it

Erich G. Yeah I should have done a blues tune. Probably would have been more useful to me. I had just started working on this song and thought it would help with a deep dive which it did but man, it took me a whole day to get half of the chorus and I didn't even try to add any chord phrases. I was just glad I got to bar 16 and stopped.

EDITED

Well if you mean writing out a song with a walking bass, I'm doing it. Here's what I have so far. Kinda simple but still took me forever and I've got 16 more bars to go. Oy Vay

I finished it so I updated the link.  May still tweak it based on how it plays but if anyone wants to give it spin , here ya go.

Maybe it's a format issue. Can you phone play mp3's. I assume that's the format

Suppose that depends on the use case for the 335. Straight up jazz then use them but if for blues/rock then probably not. His strings are gonna be hard to bend but if you're not doing that then use them.
