now gloriously proclaimed in C major. With a sudden switch of tonality to F major, however, the piece is propelled into the next section, entitled "Vision." This is a somewhat developmental passage which gradually incorporates several of the main musical subjects of the symphony together and which is composed of unstable, shifting harmonies. It is during this portion of the piece that the organ first enters, adding even more depth to Strauss's already enormous performing forces. There is an abrupt shift of mood and character as the section titled "Mists Rise" begins. This atmosphere of tension and anxiety continues to grow through the next two sections ("The Sun Gradually Becomes Obscured" and "Elegy"). By the time the piece reaches the "Calm Before the Storm", a combination of a motif heard during the Elegy and the stammering oboe motive heard previously at the peak is repeated ominously and quietly in a minor key. In this section, ominous drum rolls (distant thunder), stammering instruments, isolated raindrops (short notes in the upper woodwinds and pizzicato in the violins), flashes of lightning (in the piccolo), the use of a wind machine, and suggestions of darkness (through the use of a descending scale motive reminiscent of the opening "Night" theme) lead the piece into the full fury of the storm. There is also a long dominant pedal on the bass at the end of this section; we are moving back to the work's original key of B minor. Recapitulation "Thunderstorm and Tempest, Descent" marks the start of the last phase of the journey described in An Alpine Symphony. It is in this passage that Strauss calls for the largest instrumentation in the entire piece, including the use of a thundersheet (Donnermaschine), a "thunder trio" (two sets of timpani and a bass drum), the wind machine, piccolos (lightning), and heavy use of organ. Heavy downpours of rain are depicted by rapid descending scale passages on the strings (again reminiscent of the opening "Night" theme). In modern performances, these storm sounds can be supplemented with synthesized sound effects to create an even more tremendous effect. This section would also mark the recapitulation of the tone poem, as it brings back the elements that were previously heard in this work. As the sodden climbers quickly retrace their steps down the mountain (as an inversion of the "Ascent" theme is heard in the work's original minor key) and pass
