Chance me for RD 2021?

I wanted to post my statistics for college as I am a high school senior and want to know what I can feasibly get into. My general overview is that I have pretty good stats and E.C’s (Extra Curriculars), but Im not developed enough in one area
Objective:
ACT: 34 composite (35 English, 31 Math, 36 Reading, 33 Science)
GPA: Unweighted 3.7 (my school has a college grading system, so if I went to public school it would be in the 3.9’s)
Weighted: 4.32 (same issue as above, would be more in the 4.7’s - 4.8’s, but I could be wrong)
School Type: Private, International Baccalaureate
Rank: 4/5 out of 75 (all IB students, so all very smart)
Intended major(s): 1. Business, 2. Econ, 3. Music
Location: California
Ethnicity/Race: White
Income Bracket: Middle- Upper-Middle

Awards/important recomenders:
Outstanding Scholar in IB Business Award
Outstanding actor in lead role in school play award
Honor roll all 4 years
All State Orchestra member
2nd place in several speech and debate tournaments
Stanford Econ professor who apparently loved my research paper
Teacher recs all 10/10 to at worst 8/10

E.C’s:
Have Played Double Bass for around 10 years, as was principal at Stanford’s youth orchestra and was second chair in their university orchestra
Have toured internationally with another orchestra
Principal (first chair) for some smaller orchestras as well
Vice President of Econ and Stock Market Club
T.A. for IB Econ Class
National Merit Commended Scholar
Have a 3.8 GPA/transcript at Stanford, as I already took classes
3rd degree black belt in Taekwondo
Lead Actor in school play

I have more small stuff like volunteer activities, but I don’t remember them right now. My overview is that Double Bass is a rare instrument and is desirable, but I’m not perfect/not developed enough

Also Important: The two reps I have met with from Dartmouth have asked my name and I have emailed them a lot because they also play music, so they do know me a little bit

Thoughts?

Thanks so much
