I have an adafruit music maker shield on an elgoo r3 uno, configured for midi test, I can upload the code to the UNO without the Shield, I can upload and run other examples on the UNO. But when i plug the shield into the uno i get avr dude error 0x00 failed to sync
Port is correct, board is correct, cable is fine , code is Adafruit midi test example
#2 - RX JUMPER, GIOP101 - 3V JUMPER as 8nstructed by adafruit tutuorial
Please help 
Welcome
Is this the shield? Overview | Adafruit Music Maker Shield | Adafruit Learning System
Is this the wiring that you followed?
The usual reason for upload problems caused by a shield is that the shield uses the Uno's Rx/Tx pins; that however does not seem to be the case here.
Hence I suggest that you double check that your soldering did not short anything on the board, specifically between Arduino pins 1 and 2 on the shield. Also check your other soldering.
Note:
Next time please provide links to the products. There is always the risk that we find the wrong product and base advice on that.
Yes, that is the shield
No, its not a soldering issue, did a continuity test on every pin while stacked all showing correct voltage
Extra note*
the reset button on the shield is functional and communicating with the UNO board I can push it and i see the L-LED do its reboot flashes also, i have attached the error code message for review

Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I don't think that I can't help you further as I do not have the board; sorry.
Continuity tests are not done with "voltage" 
They are done by measuring resistance.
Continuity tests are done by passing low "voltage" through a circuit and measuring resistance. And thanks for your time
