Listening to different genres of music helps your child to develop good listening skills and distinguish different sounds and language patterns. When children are able to hear and discriminate between sounds and patterns within music, speech and language they are developing an understanding that each letter has its own sound.
Hearing and identifying different sounds and patterns within language helps them to develop the skills to distinguish the different sounds within words. As they begin to listen carefully to sound patterns they will begin to identify that there are sounds at the beginning, middle and end of words. Once they can identify individual sounds they will begin to identify where else they can hear the same sound.
'My name starts with a B. Bat and book also start with a B.'
Being able to identify sounds within words and individual sounds helps a child learn to spell words, read and write.
