Three Neglected Sonatas for Tuba and Piano

This is the revised proposal, and I need you to help me complete the revision according to the requirements.please very careful!!)

1. The blue part is the content that needs to be added, and the red and orange part should be clear to you.

2. You need to add recording links for each track to the bibliography.(probaboly last music piece you cannot find a recording,try your best)

3. Here are three sonatas pieces. 1. Sonata for tuba and piano by Walter S. Hartley. 2. Sonata for tuba and piano by Robert Sibbing. 3. Sonata for tuba and piano by Igor Rekhin.
