How to deal with out of tune: If you want to stay out of tune, you should practice scales mainly by inhaling and vocalizing. Find some stereo, or electronic organ, piano software or something, it is easy to judge whether it is out of tune. Play the seven scales of do re mi fa so la ti do repeatedly. At the beginning, play one by one, and sing the tones of the scale with "A" until you hear what you sing and play. * * * Sound is something that can be recognized when two sounds of the same scale or similar amplitude are put together. It feels like a bee flapping its wings at high frequency near its ears and head (probably two sound waves with the same frequency overlap and interfere with each other), but this kind of * * * sound will not be generated between adjacent scales, so if you are not out of tune, you should not be mistaken. After each scale is determined, we begin to connect continuously and sing do~do of eight scales in one breath, each lasting about one second. After repeated practice, you will find that most popular songs are composed of these scales (of course, there are also high octaves or low octaves). Now as long as you give a melody, you can express it in do re mi immediately.
In fact, singing is mainly about intonation and rhythm. These two points can only be regarded as singing, but feelings are the highest realm. Art is endless, and love is the other side. If you want to sing to a certain level, you can find a professional singing teacher for training if you have the conditions. The vocal music teacher of Beijing Orange Tree Music is not bad! Pitch is often the ear. In fact, when singing, ears are more important. We often neglect to use our ears when singing. Only by listening carefully to your own voice can you grasp the intonation and mood (I must have heard that people who sing with headphones drown out their own voices, so they are out of tune).
