The chord is the scales skeleton. The chord tones are the most "right" to play so to say, the most inside of tones for each chord. In order to play outside for example so it requires that you know which the inside tones are and it is therefore of utmost importance to know those tones even so in general matters. Learn the chord tones for all the chords in the same way as you learn the scales. Start with triads in major and minor and go further with 7th chord tones to m7, maj7, 7th and m7b5 chords to start with.
…and I recommend to check out these chord tone boxes all over the guitar neck.
In this lesson I´ll show two alternative arpeggios to the Gm7b5 chord. I start from Gm7b5 chord and the locrian mode in G minor.
Down below is the Gm7b5 arpeggio.
The Eb7 chord arpeggio is quite near the Gm7b5 and it´s great to use to the Gm7b5 chord. The thing with finding new arpeggios to the chords is to find new sounds to soloing with and you also get new soloing ideas.
You can also use the Dbmaj7#5 chord arpeggio if you want to sound a bit outside from the locrian mode. With this arpeggio it sounds quite different from the Eb7 arpeggio. The #5 tone in the Dbmaj7#5 it´s setting the character to the arpeggio when it´s the major 9th to the Gm7b5 chord and in the locrian mode it´s the minor 9th tone so that´s making a quite different sound.
If you´re playing with these alternative arpeggios you will get another sound to the Gm7b5 chord. I show these arpeggios how they sound to the backing track in the video lesson. It´s a modal comp in that backing-track and that´s the most certain when try these kind of arpeggios but they can work good in songs with more than one chord or keys as well but you should be aware of how it sounds and open your ears to listen if it works or not.
This is a great way to develop the arpeggio playing to find new arpeggios from your common or basic ones that you´re playing.
Hope you find this lesson useful.
