......play the meaning of th notes ~pablo casals every pair o notes creates a distinct feel tht u can exploit to create a different feel e.g. 1-5 [ thats note C & F if u take C maj scale] always sounds "good" ... try out each interval by playing e.g. C-C, C-C#, C-D, C-Eb etc etc & try to notice the emotion or "feel" it produces.... njoy! Sound quality of intervals
