There are spacious places in the world, where outcrops of woodland can be heard singing together in strong winter gales. Upland places. Uninhabited places. Naturally exposed, where the upper reaches of the land meet with the sky. 
Singing, to trees, does not involve what we have as vocal chords, or hitting the right note, or picking the right moment to come in. The wind is the conductor. The choir are the trees. The voices are the trunks, branches, twigs, and leaves. Basses. Tenors. Altos. Sopranos. 
The physical form of each tree is complex and varied, in thickness, texture, shape, and give. The more slender the form, such as a twig, the more it gives. Each shapes the flow of the wind, in particular ways. Each creates vectors. Lattice patterned chords, invisible, made of nothing but turbulent, vibrating air. Take just one tree. One form, that sings with ten thousand different voices.    
In a wide open landscape, where three audibly separate outcrops of trees can be heard all at once,  all catching and turning the wind into sound, a sense of three dimensional space can be heard, and felt. Heard, as vast banks of air move over wide expanses of ground. Felt, as deep dark rumbles. As rich brown surges. As delicate, detailed whisping textures. Rising. Falling. Rising. Blending, from one aural shape, into another. 
* We made this recording at the end of December, leaving the Lento box alone and overnight, whilst up in the Peak District. We're really happy the Lento box was able to capture this sound scene so perfectly in the strong winds.
