When it pertains to becoming an excellent jazz improviser, it's everything about finding out jazz language. So unlike the 'half-step below approach' (which can be outside the scale), when coming close to from over it sounds much better when you keep your notes within the scale that you remain in. That's why it's called the 'chord scale over' technique - it remains in the range.

So instead of playing two 8 notes straight, which would certainly last one quarter note ('one' - 'and'), you can separate that quarter note into 3 '8th note triplet' notes - where each note of the triplet is the same length. The first improvisation strategy is 'chord tone soloing', which implies to compose tunes using the 4 chord tones of the chord (1 3 5 7).

For this to function, it needs to be the next note up within the scale that the songs is in. This provides you 5 notes to play from over each chord (1 3 5 7 9) - which is plenty. This can be related to any kind of note length (half note, quarter note, bookmarks eighth note) - however when soloing, it's generally put on 8th notes.

Simply come before any type of chord tone by playing the note a half-step below. To do this, walk up in half-steps (via the entire colorful range), and make note of all the notes that aren't in your existing range. Cm7 voicing (7 9 3 5) with single melody note (C) played to fascinating rhythm.

Jazz artists will play from a wide range of pre-written melodious forms, which are put before a 'target note' (usually a chord tone, 1 3 5 7). Initially let's establish the 'right notes' - generally I would certainly play from the dorian scale over minor 7 chord.

Many jazz piano solos feature a section where the tune quits, and the pianist plays a series of chord voicings, to an interesting rhythm. These include chord tone soloing, technique patterns, triplet rhythms, 'chordal appearances', 'playing out' and much more.
