the orchestra has 4 families. the strings, woodwind, brass and percussion
TRANSCRIPT
The stringsThe strings are the foundation of the
orchestra. With their enormous sound from the lowest notes of the double bass to the highest sound of the violin.
Their tones go together so that the violins overlap with the violas and the violas with the Cellos giving consistent background.
The woodwind
Unlike the strings, which form an unified family ,the woodwind instruments are so varied that they are hardly a family at all.
In the group they vary from the high skirling of the piccolo to the low growling of the double bassoon.
The brassThe brass is the glory of the orchestra.The instruments are magnificent to look at
the shining bells of the trombones.Apart from the trombones, all brass
instruments change key by means of valves.
percassionFrom the thunders sound of the bass drum
to the little sound of the triangle . Like the trumpets in the brass section , the
drums are basically military instruments.
