Psalm Singa
As the post to which you are replying had noted: the OT contains prescriptive commands for BOTH unaccompanied sung praise and accompanied sung praise. It is not one command or the other that is normative but rather both are. The OT is explicit. Although there are a number of places where we cannot determine whether praise is accompaied or not, God clearly commands and commends His praises being sung both ways: unaccompanied (Ps. 57:9 appears to be set outside the sanctuary and may have been unacompanied as does 42:8, 77:6) and with instrumental accompaniment (Ps. 33:2, 71:22, 98:5). Outside the sanctuary, (unless you want to advocate that the Jews ONLY sang the psalms in the sanctuary), it is GNC reasoning from the data to conclude that the choice of unaccompanied worship or accompanied worship was left to the worshipper in the OT and remains left to the worshipper in the NT.
Can someone cite a Scriptural example of musical instruments being used in the OT un-connected with the sacrificial offering and clearly in the context of a corporate worship gathering?
