The cello quartet series continues on YouTube with Song Without Words.
If you are wondering how I created it. I practiced each part separately and then recorded each of the parts on different days. I used a conductor video to synchronize the parts as I was playing. (Thanks Steve!) Then I used OpenShot Video Editor to combine the videos into one quartet. I would estimate that it took about 6 hours once I started making the recordings. I am not sure how much practice time I used to get ready to record.
Now it is possible to practice with the individual parts as well as the full quartet.
