K. 12, Sonata in A

K. 12, Sonata in A

This piece like K. 11 starts with an andante tempo.  However, K. 12’s first movement sings more hope.  The tempo is as brisk as it could be, while still being slow.  Its pace gallops as the controlled gate of a show horse whose owner releases the reins for just an instance.  The rider (soloist) eases out some speed to show the crowd what the stallion could do, but restrains the horse for beauty and grace.  The allegro movement is the horse’s trotting finale.

I listened to this piece in both a violin and a flute version.  To me, the flute feels happier, while the violin holds more drama.   I am confused to exactly what kind of sonatas K. 10-15 are.  But, it seems that here was where Mozart started fiddling (no pun intended) around with other instruments.  I always wondered how does a composer decide which instrument to use with which music.  Clearly, certain instruments carry various moods.  Were the K. 10-15’s Mozart’s years of instrumental experimentation?  A yearning to feel what the instrument had to say?

How long does it take the average person to find his or her voice?  To figure, out what he or she can say with the various talents provided?  And, how can we ever know what we're supposed to say or by which means we are to express it?
