Could anyone explain soloing

the only way is to mess around with the scales and find patterns that sound good to you. It's like when you are a kid, and you get a ball, you just play with it, no rules, you just have fun. You need to do the same thing with your scales, mess around, play with them, it doesnt matter what is sounds like at first, just get the feel for it, then you will start coming up with hot little licks and runs inside the scale patterns, and then you can solo.

The word "modes" mean moods in Greek. so if you think about the mood you are trying to set with your solo you can play the mode that fits. Example if you are playing in the Key of G chords of G, C & D a typical 1, 4, 5 rock or country song. Now if you play a G major(Ionian) scale but starting from the B and play to the B(Phrygian) you will have a Spanish Latin feel like Santana. now if you start E and play to the E(Aeolian) you will have a minor blue/rock feel. Just remember the the key word is mood or feel Hope this helps

There are a few different ways to apply modes as a step beyond the pentatonic's.

You could do as the previous poster suggested and just mess around with the scale shapes; using your ear to guide you. However, that's a bit unreliable, especially for adult learners. It's true that you could develop an intuitive knowledge of music by playing around with scales, but you would have to be extremely gifted. Your time may be better spent studying theory and using the more traditional routes to learning music.

Very few musicians get by on their musical athleticism; very few athletes get by on their athleticism. People enjoy sport as a hobby or exercise, but professionals spend their time working on the mechanics of their sport.

I would suggest figuring out how to make the modes by adding notes to the pentatonic scales. Let's use Ionian as example. The C pentatonic scale is CDE GA you can just fill in the spaces with the notes F and B and you have an ionian scale. CDEFGAB.

You should also learn how the modes sit around chords. Same example as above: C E G, add D F A and B. Make the scales fit into actual chord shapes. This is the essence of the "CAGED" system.

Be exact in determining what finger plays what note, and play the same pattern until mastered while recognizing chord tones.

Now we apply that to actual music: play chord tones on down beats and using non chord tones as passing notes. Start off slow, really slow, you're creating a melody. Then build scaler phrases from there. Slow melodies should turn into fast solo's. Eventually, you will find soloing easier because all of those chord and scale connections will train your ear to match scales with chords.
