I am not good at pronouncing th sound. I heard that when native speakers make th sound, you stick your tongue between your front teeth and pull quickly. It is easy to say short sentence like "Thank you "
But for example,like the , it often appears so often in a long sentence, I tend to forget to stick my tongue . Do you have any advice?
Making th sound is really tough for Japanene(´ι_｀ )

Hmm, well I have been told by many 日本人that I have good 日本語の発音 and the way I learned was by singing along to 日本の曲.

I would pick a song that I liked, find the lyrics on Google, and then play the song. When the singer started singing, I'd try to read the lyrics and sing along.

Because I can't read Japanese quickly, the singer probably sings faster than I can read, so maybe I can sing the first two words with them but before I've even read the third word they're already on the next sentence lol.

So I have to restart the song many times and just sing until I can't keep up anymore.

Little by little, I memorize the song. Eventually I'll be able to sing the entire first sentence, then the second sentence, then the entire first verse, etc. Until finally, I can sing the whole song.

To memorize an entire song it takes me at least couple weeks (depending on how often I practice), but once I've memorized it, I don't have to read the lyrics anymore. I just listen to the song and sing.

Once I am able to do this, I can focus a lot on my pronunciation. I try to pronounce exactly like the singer. I sing the song over and over and over until my pronunciation is almost perfect.
