Do you think it is useful for daily's practicing scale ?
I am not a musician and know very little about violin. But I have a teenage son who is learning violin. It is very hard for me to help him for his violin practicing.
As a software engineer, implementing a software application is my strength. So I created this for him: http://violin.duolando.com. The idea is that I play same notes using my mobile phone while he is playing with his violin and listening carefully.
What do you think it? Is it useful for a violist's daily practicing?
It is not too ideal, as the violinist's finger placement for pitch varies according to the scale being played. So the G# for the A scale shouldn't sound the same as Ab for the F minor scale.
Interesting web-site. It can give your son a reference tone. That being said, western scales are built on octaves that contain two four-note sequences. Major scales all have half-steps between the third and fourth and seventh and eight notes of the scale.
Thank you very much for your comment! Duolando Violin has also a tuning function. For example, when G# shall be higher in A major, you can go to this note and choose from main menu at top right corner and then "Tune this scale". This will show a new window, where you can tune this note to be higher or lower. You can also share the tuned scale to others by selecting "Share my tuning" from menu. It's a simple link, which can be shared in Facebook, Twitter, email, and etc. A recipient can use the tuned scale simply by clicking this shared link.
Sorry to be "master of the obvious" here but your son's teacher should be showing him how to play scales in tune and how to practice them for improvement of intonation, tone, etc. The book "The Violin Lesson" by Simon Fischer would be a wonderful holiday gift for him.
I think a little bit of note matching might be OK, but it can be overdone. Learning to match an external sound is not the same as pre-hearing the right note "internally" before you play it.
