Good, but misclassified
Hey man, good stuff! I like the laid back feel of this and the nice chilled feel, however I do have one complaint.
This music is NOT JAZZ, so do not classify it as jazz. I'm really apalled to see that the world sees something like this as jazz. I'm not trying to say you suck, but that this is more elevator music or lounge music. NOT JAZZ. Jazz follows a blues scale and has swung notes. The saxaphone in this is playing straight 8th notes, not swinging them.
If I were to classify this, I'd say this was a be-bop or a fusion tune. It actually borders on rock and jazz, but it does not exactly fit into either one.
Now on to the positives: You've got a very smooth and flowing feel. Just like your comments it is playful and a bit of sad and happy. Your soloing is well put, I like it. The trumpet solo it's too fanfare-like. Your sax solo is a bit repetitive too. However, i see that this is lounge music, and I respect that . I don't like repetivive, but if it fits the song, then by all means do it!
Good piece of work, I like it a lot. Just re-classify this sucker and I'll be as happy as a volcano.
P.S - I'm a music major and I play Jazz Drumset, forgive me if I was too harsh on your classification of jazz. I'm here to help, not to burn your face off! =-D
