I'd like to see a great player do the following:
-Take various song types (praise, worship, etc.) and run through various techniques, including various bass lines, fills and riffs. When playing a riff, identify the key and scale used (e.g., "here's a funky riff in G using the blues scale").
-Identify each chord by name (e.g., F7alt, D6, etc.). Alternatively or additionally, identify the progression (e.g., 2-5-1) and the key.
-Maybe separate these 2 lessons into 2 or more products and really go in depth into each.
