Yeah... at the time, I was a TAXI member and used their listings (free to anyone who wants them) to pick song ideas to write to.
Having the idea given to me in the listing.... usually a description... film needs ending song about..... kind of thing, made the search for the idea easier. Then they also have a deadline date that the song has to be submitted by.... in most cases a week or more but in some.... just a few days or less.
This is one>>> early version:
http://soundclick.com/share.cfm?id=11198785 3 day deadline from when I saw it and decided to write it. The story was man works for pharma company. He has 2 sons and a wife. Wife and one son are killed in auto accident at start of movie. He has a very hard time with the deaths of his family and the memories. His company is developing a drug to selectively erase memories. he volunteers for the clinical trials. >>> end of movie, the drug works but has side-effects that include flashbacks.... he is playing with his son on the floor, he gets up and walks to the window and simply stares out at the day... it's raining and grey... movies fades to black.
Side bar: they liked the song but it was not as indy, cutting edge sounding as they were looking. Too much ballad/country in it. This was a solo write.... co-writer was busy. 3 days start to finish.
Having the topic and a deadline forces you to write, record, and polish it quickly.
I wrote many of them alone, but a number were done with a co-writer.
To answer the question..... yes, I saw a significant improvement in my skill by doing the 1 song every 2 week challenge. Some were instrumental, and some were full blown lyrical creations. Only a few are up on the net. I don't place all my tunes on line.
Last year, I did not do the challenge, but focused instead on quality of writing rather than quantity. Both are important.... but.... as a result, the ones I wrote, I think are among my favorite self penned songs. Pat thinks so as well....
they include: Footsteps* updated version (also originally a "TAXI listing write to"..., Come & Go, The Best Christmas, and Ode to Wolf.
Take your challenge....be reasonable and realistic in your goal. You want something to be a challenge but not to become a chore....... do it, stick with it.... for one year.... save the first tune you write and compare it later to the last one in December 2013.... and compare for yourself. If you work diligently during the year, study and read books by hit writers, hang out and discuss songwriting with other writers, apply what you learn.....it'll be worth it.
Right now.... as of Jan 1... I have 3 songs started.... some are just rough draft ideas.... others are near completion but need a verse rewrite.... I don't have a set number goal, my ongoing goal is to simply write more music to the best of my ability, and to continue to learn from the masters in this business.
