Before we go any further, however, we may cast our eyes forward and see where the basses are to re-enter. Something will have to be added to the strings on the last beat of bar 97. But let us make that “something” the least possible—say, an increase from p to mf, with the addition of a wood-wind quartet (clarinets and bassoons) to our four stringparts. Four bars later (last beat of bar 101) something still more will have to be added. As we do not wish to anticipate our streak of brass lightning in bar 106, we had better bring in our basses and horns here. This is not a very great addition of orchestral strength. But we do not want a very great addition. And we can make its presence quite perceptible by simultaneously jumping the first violins into their upper octave, and at the same time increasing the pungency of the wood-wind by introducing the oboes and flutes.
