This is an application about musical instruments. Do you know how to use sax?
Before starting any tunings make sure your sax is nicely warmed up. A cold sax will always sound flat. Also, if you are practicing in a really cold room you might find that the top of the sax is warm but the bottom is cold. This is going to make your low notes flat, and your top notes sharp! So if your sax is cold, blow some air through it to get it up to room temperature. You could also do some long notes to get the whole instrument up to Temperature. Pushing your mouthpiece in and out could also change the overall pitch.
Not just sax, you can always find the instrument you like here. Subsequent richer features will be released soon. If you have good suggestions, please contact us at maybelsmge@zoho.com
