the most common way is the "2-5" walk up....
for example...
Key of Ab
2- Bb / Ab Db F Ab
3- C / Ab C Eb Ab
4- Db / Ab Db F Ab
b4- D / Ab B D F Ab
5- Eb / C Eb Ab
to modulate to Bb, I might use F-G-Bb (both hands) as a melody line....and then do the walk up in Bb....
Another thing I might do is use the lick/route in "It's About Timer For A Miracle" When they are bouncing on the Eb (5) to get to the Ab (1)...
then another popular one is the "Chicago Bump"
then you got the route John P. Kee's band do... (2 -b3-3)
There are so many ways....lol
