You can also make a song to sent to someone you love to,like a present in birthday, christmas...or to show your love. You don't want to make any song, but love music, this can be your music library, just show your favorite song, your music taste which can show your emotion, your feeling in some moments without any words.How to make a song ? We will connect to each other, then you can use your smart phone's mic, or special mic for good recording, the artist will use a small device which connecting the guitar, piano...to smart phone by bluetooth or wifi, you hear the instruments sound and the artists hear your voice, the app will record and mix them together.Let's rock.
