It is well known that many authors listen to music while writing. For some, music serves as inspiration. Some use specific types of music to match the mood of their writing. Still others find that music helps their writing to flow. I have found that I fall into that last category. I can write with or without music, but I more easily get into a writing rhythm (no pun intended) while music is playing.
The type of music authors use varies widely. Stephen King, for example, is known to play loud, hard rock or heavy metal music while writing. While that type of music is definitely among my favorites, it is banished during writing sessions. It's not the volume, it's the lyrics. I can't concentrate on my own words when other words are competing. For me, writing music must be instrumental.
Classical music is among my favorite writing music, especially Mozart. Most of us have heard of the Mozart Effect. Listening to Mozart's music for 10-30 minutes is known to temporarily increase creativity. I can attest to being susceptible to it. Other classical composers are also included in my writing playlist. I especially love violin music so I'm a big fan of Joshua Bell. His CD Romance of the Violin is probably one that I play the most while writing. In fact, it's playing as I write this.
My other favorite violinist is Eileen Ivers. Her electric fiddle playing is perfect for when I need to find a faster, edgier pace to my prose.
Occasionally, I like to write to CDs of nature sounds, especially if they are mixed with instrumental music.
I don't know what it is about music that aids creativity in writing. Perhaps those who have studied the Mozart Effect can explain it. All I know is that I feel a definite difference when I write with music on in the background. My words flow more smoothly, ideas come to mind more readily, and I feel more relaxed as the music weaves it's magic spell.
