What do you suggest if i have add and adhd and i'm a musician will this the drug strattera (atomoxetine) help me with memorizing music a ?

Not exactly.: Strattera (atomoxetine) is a a non-psychostimulant which means it helps increase attention (reduce distractibility) without acting like an amphetamine (body wired, stimulated). You may pay more attention to the music heard, but recall of rhythm, tempo, or lyrics may take memory-repetition tasks; otherwise, you risk recalling either the beginning (primary) or end (recency) of the song, but in between.

By impoving: concentrating ability and decreasing destratability you may be able to learn music better but still takes repetition
