Explanation:
1. If you take wood then I would say maple, rosewood, cedar, walnut can be used to make "String instruments". 
Reason: 
The wood that we choose should be perfect and should give long-life to use the instrument.
2. If we consider about strings, then I would suggest that the material that you choose should be "ductile and hard".
Reason:
Thin wires can be drawn. 
3. In case of Brass, it should be "malleable metal", so that the outcome of the instrument will satisfy the need.
