Hey Matt, I know some scale shapes now by heart (major and minor pentatonic, major and minor scales, harmonic minor to be exact). I did do a lot of improvisations some time ago but I have come across a lot of backing tracks which are weird in the sense they stay in the same key for almost the whole time but the scale just doesn't work on them.
So I decided to memorize some arpeggios. But I am having some troubles. My questions are:
1. I learned scales by remembering how they sound, like the harmonic minor and the pentatonic minor, I can differentiate between both of them because their notes together sound different. Arpeggios sound a bit weird to me, even though they have the same notes in their respective chords. The sounds of the notes in them doesn't seem to fit very well according to my ear but they do sound good when soloing. So that's kind of hindering my ability to memorize the shapes. Any tips? Or should I just hang on till they sound and feel natural?
2. The idea of changing the whole arpeggio whenever the chord changes is sounding huge to me, I mean theoretically it seems like a major task of changing the arpeggio whilst the song is playing. Also if I don't know the chords in advance, I won't be able to predict what arpeggio to use. These things kind of scare me. Is it really that complicated when using arpeggios in improvisations?
Sorry for the long post and the long questions, but I started using arpeggios since last week and they've been really weird to me, specially because I'm so used to using scale shapes on the neck to solo. Any help would be immensely appreciated
