The form I have used on a Lydian scale is: e|------------------------------3-5-7-| b|------------------------3-5-6-------| g|------------------2-4-5-------------| d|------------2-3-5-------------------| a|------2-3-5-------------------------| e|1-3-5-------------------------------| Arpeggios are 1,3,5, and 7th note in a scale so it looks like this: e|----------------5-| b|------------3-6---| g|----------4-------| d|------2-5---------| a|----3-------------| e|1-5---------------|
